Seriously? I just ordered a Nexstar 8SE 3 days ago and now this ? If I would have known I would have definitely waited.

I'm not so sure yet. Unless you want the 9.25? OTA looks the same and still no vents? Shame.

Mount will be interesting, slew noise and accuracy. Worm gears should help.

Depends on the price for me.

It will be interesting where it fits in the product range from a price perspective.

Seems a little crowded to me.

I'm guessing...

Nexstar > Nexstar evolution > cpc > cpc deluxe

But will a HD version come along?

The wireless capabilities allow you to run it using a smart device. So basically just a built in SKYQ Link Wifi Adapter.

Still...I think they are priced too high. They should have replaced the SE line with these at a higher price.

I just got back from NEAF. I have to say its a much beefier mount and the 8" and 9.25" will come with 2" steel leg tripod for extra sturdiness... This is what I posted over in the CATS forum earlier today on this mount:

"Just got back from NEAF. Spoke with the celestron people about the new evolution mount. Will come in 3 configurations, 6" with the smaller tripod and 8" and 9.25" with larger 2" legs mount. It comes with a hand controller, but is meant to be used wirelessly with your smart device. Also the gears are brass and therefore you will not experience the same annoying backlash issues as with existing SE mounts. Another neat feature is enclosed lithium ion battery which is supposed to provide 10hr of use. So you will not need to bring power source as its embedded in the single fork arm. There are clutches on the azimuth and declination fork arm like the cpc which means you can move it manually, another nice feature. I lifted its beefy from 25lbs for the 6" to,46lbs to the 9.25". And yes, the 9.25" clears the base at zenith (barely)...

Celestron people were pumped about this product... Looks like the nexstar 6/8Se is going to be retired very soon... Oh by the way this enclosed battery and wifi capability is going to become a more integrated feature in upcoming celestron mount/scope packages..."

Interesting, indeed! I just happened to see it this morning on the Celestron site (which is now down at the moment, no doubt thanks to you guys).

I've been looking for something lighter (or at least lighter individual pieces) than my big CPC1100, but more capable than my little 6SE. I really like the lightness of my 6SE, but it just doesn't have enough aperture, the backlash drives me to drink (i could almost have a drink or two in the time it takes to move in the opposite direction), and the lack of clutches is irritating.

I'll have to keep my eye on this new arrival. If i end up buying one, it sure won't replace my CPC1100 which i love, but it might save my back some strain when doing less formal viewing.

I hope the hand controller is standard, because palmtops/tablets/etc aren't yet a part of my starwatching retinue.

But now i'll have a quandary -- 8" or 9.25"?

I'd read it as "the hand-controller is an optional item that you'll have to buy". As long as it's compatible with the current HC (other than the StarSense unit), I'm okay with that - used prices aren't all that bad.

imo after using CGE/CGEPro/SE/SLT mounts with either SkySafari or SkyQ, there are still many instances where I'll take the hand controller over a phone or tablet - imo it's just faster and simpler for quick setups and taking a peek - so much less tapping on a screen; besides the HC is quite though and you can just dangle it out of the way (haven't we all done that!) instead of having to find a place to set a phone or tablet down.

I think this shows that Celestron is listening to their customers! No battery and hc wires? Sign me up!

And furthermore.....if history is any indication and I certainly believe that it is then it stands to reason that the 9 1/4" model will be the one to avoid if a steady view is foremost for you. They may sell it but that does not mean it should be sold and there are plenty of examples in the current lineup to help slam home that tidbit.

Did someone mention price? That's the key decision for me? Batteries and wifi are nice but don't mean that much to me on a personal level as they're simple accessories.

If the clutches allow the OTA to be moved and still keep the position that would be nice. I'd also want tube vents and quiet slewing?

Celestron site list them at 1200/1600/2100

The Evolution 6 sells at the price of the Nexstar SE8. For the same price, do you prefer 2" of aperture or better gears/WIFI and a battery?

Ben,

With video observing you'd definitely prefer a more robust mount with better gears to a small increase in aperture. Smoother tracking will allow you to push your integration times up. In a light polluted area that will mean you will be able to use more aggressive filtering ... which means better views of fainter objects. This of course assumes that your video camera can take advantage of the increase in integration times.

Remember though that this new series is still an alt az mount so there are the inherent limitations due to field rotation ... so even with better tracking you're not going to be able to go with multiple minute integrations. But being able to consistently use 30-60s integrations is IMHO a sweet spot for video observing ... with fast optics it really opens up a wide variety of objects even under pretty bad light pollution.

The SE mounts may if they are a good example and well setup be able to go into that range. The Evolution with it's better gearing should be able to do that consistently. This assumption is based on the comparison of performance between the 6/8SEs and the Meade LS series.

With scopes of this size a 2" increase in aperture will mean almost nothing to a video setup ... smoother tracking will however make for better images regardless of how good the optics on the mount are.

Just picking up on this thread. Very cool!

Seems to me like a replacement for the CPC line, at that price. They have the worm gears (HUGE improvement!), but use the single fork and dovetail which means it will be easy to balance or to move the OTA to another mount. The one thing that pushed me away from the CPC mount originally was that locked-in dual fork design.

I think we need to see if there is any increased stability with the 8" and 9.25" Evolution on the supplied tripod. Lots of 8se users have used the sturdier CPC tripod for greater stability. They have reported some increase in stability, but also said that it is not the complete cure.
I think the Evolution range is a replacement for the se range and not aimed at the CPCs. My choice of a permanently mount scope would still be a CPC over the Evolution.

I'd agree with that, for a fixed mount, or even a serious field expedition. I really love the stability of a fork mount. So i won't be replacing my CPC1100 anytime soon either.

However for less formal field use, my back definitely does NOT like the heavy CPC1100 65lb fork mount anymore. A single-fork mounted scope that can break down into lighter individual components would be real nice (before my poor back decides to break down into lighter individual components...).

Well I thought the product line up looked a little squashed. Still I wonder whether they'll still offer the nexstar SE range?

Wouldn't a unified set of OTA's on the two alt az mount types, evolution and cpc HD work well?

It appears from Celestron's marketing info and reports from NEAF that the Evolution series is effectively a single arm CPC. By using a variety of tripods a wider range of packages can be offered. I'm not sure if there's enough arm length to handle the big C11 ota but outside of that tube the Evolution can handle the C9.25 and is a substantial upgrade from the 6/8SE mount. The positioning with the C8 ota is exactly in between the SE and the CPC series.

With better motors and gearing than the SEs but carrying over the Vixen/CG-5 dovetail saddle the Evolution will also be a popular alt az option for a variety of other (non Celestron) otas. This position will only be enhanced if Celestron also offers the mount on it's own at a reasonable price point. (note to Celestron - don't get greedy, you have a unique opportunity here). Perhaps also offer the mount only config with a dual type of saddle for either D or V type dovetails?

The Evolution also appears to be an interesting option for AP, especially in the field. Short fl refractors, other Cassegrains (RCs for example), and smaller Newtonians all appear to be possibilities on a wedge mounted Evolution. If the Evolution proves to have good smooth gearing then configurations with a wedge could be a popular option vs. lower and mid sized gems (CG-5/AVX, CGEMs, etc.).

Now't spoiling Al.

It's an interesting one this.
I can't see a single armed mount being able to give the same rigidity as the excellent forked mount of the CPC series.
Perhaps Celestron will run all the existing models along side each other for a while.

According to the description, the new mounts contain worm gears. That should be an improvement over the spur gear setup found in the 'SE' type mounts.

However, I would have to question how stable in actual use a 20 pound tube assembly (9.25") is going to be on a single fork arm mount.

Oh yeah, i didn't think about that. Unlike the big 65lb CPC fork-mount, the Evolution should actually be light enough to put on a wedge in the field by mere mortals. Maybe 20-25lbs for the heaviest single component?

Hmm. Now combine it with that mallincam i want to buy, and i could actually do multi-minute video integration.

Maybe i'll yet be able to avoid having to learn/master polar alignment...

Of course, it remains to be seen whether the Evolution mount can actually handle running at a serious angle. Assuming the thing actually works reliably even without a wedge. Who's going to take the plunge and be the guinea pig?

Really quite intriguing and compelling... there maybe a future for the Evo 9.25 for me as the GPS 9.25 is quite a beast to break-down, setup, break-down and setup for any viewing/post-viewing session.

Interesting to parse through the product details although they maybe wrong:
8": http://www.celestron.com/browse-shop/astronomy/telescopes/nexstar-evolution-8
9.25": http://www.celestron.com/browse-shop/astronomy/telescopes/nexstar-evolution-925

There is only a 6 lb difference between the 8" & the 9.25", where as I thought there was at least a 10 lb difference in the OTAs alone.

Also of great interest are the specs on the 8" 2nd'ary mirror from the above:
Secondary Mirror Obstruction 2.5 in (64 mm)
Secondary Mirror Obstruction by Area 9.77%

which must not be right - the obstruction size (2.5") has not changed yet the area they list is significantly smaller ... maybe the size of the obstruction has shrunk and they have it listed incorrectly!

Also of interest, Celestron now has a 102mm ED refractor listed at a very attractive price with mount.

Very cool - can't wait to see these in the flesh.

So what happens when the battery or its charger dies ...can it be replaced and if so at what cost...?

That is a concern of mine...the use of work gears is a HUGE improvement so is the clutch...

I could care less about controlling the scope with a phone/tablet/or a computer..

Still will not be able to balance the scope in all parts of the sky with a wedge .. a little vector analysis from high school physics tells me it just ain't gonna work

I still can't see a clear product space based on the current SE, cpc and cpc HD range?

These are rough UK prices?

8se 1200

8 evolution ???

8 cpc 1500

8 cpc HD 2050

all,

just wondering if there would be room for a dslr on the back end? it does look a little squashed compared to its older SE brother?

would love to get one and do some photography, i know i wouldnt be able to do very long exposures but 30-60sec shots plus if theres room for a focal reducer

Might have to do what i currently do on my little 6SE -- slide the OTA forward on the rail, and don't go near vertical.

Hello from SW England,

Anyone seen any indications when the new Evolution 8" might arrive in the UK ?

I've been lurking for a while and thinking about an 8SE or perhaps a Dob at 10" or 12" for similar price range in the UK.
I had just about decided on the 8SE for portability when they announce the new Evolution,
Oh decisions decisions , , !

I dont know if I should buy the 8SE now at the discounted price and enjoy it or wait (a long time ?) for the new with worm gear.

Quote ..... said
"Why would you need a hand control when you have wifi and and iPhone/ipad. "
Me ! because I have not got any of these newfangled iThingies !
And going by my experience of cameras with Li-Ion batteries in the cold at night, not to mention their lifetimes, I'm not sure I would like a built-in Li-Ion either

Quote MadHungarian : "the Evolution should actually be light enough to put on a wedge in the field by mere mortals."

BUT you would have to set up polar align manually ????
because the "SKYALIGN TECHNOLOGY" drop-down says
"OR IF MY ALT-AZ SCOPE IS ON A WEDGE?
SkyAlign is not currently available for , , , does not work with alt-az scopes on a wedge."
or am I getting confused ? I am only a bear of little brain and there is so much stuff to absorb when thinking of a new telescope !!!

Hi Chaffinch,

Firstlightoptics have them although you have to call for a price.

I think Harrison's Telescopes may be your next best bet.

Yeah,a lot more than original Nexstar.If I had these choices when I got mine,2 years ago,think I would have gone with a different mount in an Equatorial instead of the single fork arm just because of the cost.

The more I look at these, the more I wonder if Celestron isn't considering retiring both the SE and CPC lines in the not too distant future. Right now their lineup is getting pretty crowded with too many levels/prices to sustain.

For people that are looking for cheap goto setups, they have the SLT and LCM series. Those have probably eaten into the SE sales for people on a budget.

SE owners complain about the shaky one-armed mount, but the CPC is a lot heavier and bulkier and doesn't allow OTA removal or balance. *IF* the Evolution's arm is solid enough to provide most of the CPC's stability, it may meet the needs of both groups. Yes it's more expensive than the SE, but they always come in at a higher price point and start working their way down over time.

Of course, this is all speculation. Who knows what Celestron is thinking?

Here in the U.K, Harrisons Telescopes have the 8" Evolution listed at 1,799 ($3021).
The 6" and te 9.25" are not listed as yet.

Thats an awful lot of s for an 8".

The new Evolution range would have to go a long long way to be anywhere as stable as the CPC range. I, as you know, have both an 8se and the CPC1100, and to me the difference between the two re stability is chalk and cheese. Celestron may have made some inprovements in this field with the Evolution range, but I don't think the single arm mounted Evolution could ever be as stable as a twin fork mounted CPC.

That said, I also believe that the se range is aimed at a different user group to that of the CPC range. They are very good in there class, and I am the proud owner of both.

Regards. Peter.

I question the rigidity of the one arm mount with the heavier OTAs. To me, the 8SE is already pushing the limit. It would take a very bulky one arm mount to equal the rigidity of even a skimpy fork mount. I have a scheme for measuring the flex on the 6SE. I will post a separate thread describing the method and results so that others can measure and compare their mount.

Ouch !
That's new on their site.

When I first asked I _had_ checked the usual suspects in the UK but they were all of the form "come back later" ( I paraphrase !)
But still they are all saying ETAs will be announced later .

The reason I am asking for estimates of estimates (!) of ETA was to sample you're all considerable experience of lead-times on Celestron announcements in the past, ???
eg. I have experience of model railway factors who announce new products which sometimes have lead-times of a year or three or never materialise at all !

So, how do Celestron do generally ( I'm not after the length of a piece of string ! I wont hold you or them to it !!) on past performance, are we typically talking weeks months or years ?

Thanks.

Oh, PS :

It seems odd to me that they make a big deal of changing to a worm&wheel for accuracy,
yet say that it will not work on a wedge ?
Isnt the point of a worm&wheel for photo quality tracking (necessitating a wedge) ????
The previous spur gear, by all accounts, is fine for visual alt-az use.
What did I miss ???

Both my CPC1100 and 6SE manuals claim that wedges are supported with auto-align, at least with the keypad. Mind you, i've never tried it out myself. So i'd have to expect the Evolution mount to have the same functionality (whatever that might be).

As far as spur gears, i myself find the worm-drive in my CPC1100 to be much much much more enjoyable to use for visual alt-az than the spur gears in my 6SE. I'm hoping the Evolution worm drive give similar performance.

Any of the current Celestron alt az goto scopes can be tipped up to your current latitude and put into EQ mode. In this setup you effectively have the same functionality as with the gem style scopes (CG-5/AVX/CGEM/CGEPro).

If the new Evolution is using what is essentially the same NexStar+ firmware (likely but with upgrades) then the same capability would be present. Those alignment routines are One Star, Two Star, Solar System, Quick, and Last alignment. In EQ mode the preferred method for best accuracy is the Two Star with 4 calibration stars.

I asked this question in the other Evolution thread but got no response. Does anyone know if the battery can be easily accessed? While I like the idea of an integrated battery it also seems like it could be a weak point and I wonder if it's easy to get at in the event it dies. I think I read that it is "embedded" in the fork arm. I was looking at pictures but it's not obvious to me where the battery is located. Thanks.

Interesting, but a few concerns. If the wireless capability = SkyQ integrated, not sure it will be a good thing as the skyQ do not have a good review, especially compared to SkyFi. I hope the 10-hour lithium battery can be easily replaced when its life is over. And the price, seems a bit too high, as nearly everything new here can be replaced by separate accessories (wifi, battery). The only real improvement here is the worm gears. For the price, the SE series still presents very good value for those wanting light weight and aperture.

Thanks, yes, I see it now.

I have also found this in the "Description"
SUPERIOR TRACKING FIT FOR ASTROIMAGING
(snip)
you can add our Pro HD Wedge to achieve longer exposures for more detailed astrophotos.


So, either SkyAlign has been updated, or one of those others can do it ( I'm off for a read in a min. )
or, as I conjectured in an earlier post, you would have to set up polar align manually ?? That'll be fun
The plot thickens

If you use a Celestron alt az goto mount in the alt az position you have the choice of SkyAlign, 3-Star, and Solar System alignment routines. If you tip the scope up and enable EQ mode then you lose those alignment options and instead get One Star, Two Star, Solar System, Quick, and Last alignment routines.

If you look at the descriptions for the other alt az mounts/scopes they don't mention these EQ alignment options either and I assume this is just the same situation with the Evolution mounts. This makes sense since you'd have to discuss the optional wedge in the description and some folks would likely still miss that and keep asking Celestron why they don't see Quick or Last alignment options in their setup.

With any EQ oriented scope accurate polar alignment is important for good tracking (but not for good goto accuracy). The Evolution should be no different so if you were going to do some imaging with the mount on a wedge then yes you'd have to perform some sort of polar alignment. Fortunately the NexStar firmware includes the great All Star polar alignment routine so it shouldn't be a big deal as long as the wedge is reasonably easy to work with.

Has anyone substantiated the rumours the 9.25 won't support 2" accessories because of lack of clearance?

If that's the case I think that's a huge problem. Why bother even suggesting the package makes sense. How many new owners come to realise after the fact that the larger eyepiece range is effectively off limits?

I hope Celestron make it clear soon.

Thanks very much for all the info, that is good to know,
that answers all sorts of my questions

Not having previously owned a Celestron I was unaware of those features,
I was in fact about to press the "Buy" button on a 8SE on the very day that the Evolution was flagged on a UK forum that I watch.
Being primarily visual for the better part of 1/2 a century who knows what mischief I might get up to if I have the facility of AP as well !!

I had no idea you could put an SE scope on a CPC tripod. Can you really? I'll have to try it sometime. Of course, my little 6SE sitting on top of my big CPC tripod would look a bit like a bump on a log, or sort of like my spanish teacher from highschool (big body, tiny head).

The 8 version of the Evolution seems like it would be a grab and go CPC. Especially if mounted on a CPC tripod. The only thing stopping me from going this route is that Nexremote seems to have no support for the Evolution. At least there is no entry in the drop down menu for it in the software. I know that there are other remote solutions for operating your scope remotely, but I need to have the speech feature of Nexremote so I do not need to have a computer outside. Having very bad eyesight I have a very difficult time reading the HC display and the speech function of Nexremote solves that for me. Maybe going with an AVX would be a better idea for me.

The 3 bolt pattern used on the SEs is the same as used on a wide variety of Celestron Alt Az scopes (CPC, Nexstar 8, NexStar GPS, and presumably the Evolution).

The CPC tripod makes a nice solid base to attach any of those scopes to. If you can find one the black NexStar HD tripod also makes a great replacement for the lightweight SE model. The older NexStar tripod is lighter than the CPC model but is still quite substantial and if you can find one a cheaper option than the CPC.

fwiw I have 6SE, and occasionally swap out the OTA to a C8. Bought a CPC tripod, bought a SE wedge. Tried all 4 combos for a couple of months. I've since sold the tripod and wedge. It's back to the stock 6SE for compactness and weight as it was meant to be, the C8 rides on a NexSXW or manual alt-az (Porta/Voyager) as needed.

As for the new NS-Evo, I hope astronomics has one setup when it's in stock so I can check it out in person - the 9.25 looks tempting if it checks out right.

That's actually what i like about the 6SE on the stock tripod -- i can pick the whole thing up in one piece and carry it somewhere (usually out to the sidewalk). With a little Starizona LiIon battery back (or equivalent) hooked up to it, it'd be even better. But i often wish i had an 8" OTA i could put on it too when i need a little more power.

I have been using ebay LiPo packs (search "12V LiPo Battery", sold for CCTV application) without any problems as of yet. They run around $25 shipped with charger. Our astro application is low current draw, and I haven't found the need for high discharge packs even though I have them for other purposes.

That said, I still treat these packs with a little more caution and respect compared to NiMH; charge only under supervision and don't physically abuse the pack. I've yet to taken apart the ebay packs (will do soon), but iirc from reading other reports they have on-board low-voltage cut-off and charging circuitry built in.

The LiPo battery I use came from my hexacopter. It had a broken lead which I repaired but don't trust it in flight. Therefore, it has become my scope battery. I also use all the precautions while charging or handling these batteries. They work great but you have to follow the rules. A voltage monitor can be plugged in during use and when it hits 10.0V, stop and recharge in the balance mode at 1C.

I'm not sure about the eBay batteries but most LiPo have the main discharge wires and the balance cable. This cable is just a wire to each cell in the pack and is necessary for balance charging.

I will be very interested to read actual reviews of these once they have been field tested. Particularly in the 9.25.

I briefly owned an 8se but exchanged it for CPC800. While not the primary reason I exchanged it, the heavier tripod and worm gears ended up being a huge benefit of the CPC800 over the 8se. I would certainly want to use a 2" diagonal, and I currently use one that threads directly to the OTA on my CPC800. If the NS-Evo 9.25 OTA can be moved far enough forward for clearance at zenith, and it as stable as the CPC line, I could see an upgrade (sidegrade?) from CPC800 to NS-Evo9.25.

The ebay pack, like the Starizona one I've seen, has only a single charging lead in. **my best guess** is that the balance charging board in built into the batter pack (again, I need to remove the shrink-wrap on my ebay LiPo - they should also include short protection along with low voltage cutoff). I also plug the included charger thru a wattmeter to get readings on how much I put back in, and also how much a particular setup I have has drawn in an observing session - so far I've never gone above 4Ah for a whole night's use; have the numbers somewhere.:D

fwiw it was a rather eventful early days for electric R/C LiPo use about a decade ago; quite a few fires on equipment, indoors, garage, vehicles! Still remember ThunderPower's initial claim that their cell-matching assembly didn't require balance charging . Buddy of mine learnt the hard way with 2x 5s packs (10s) powering +1kW outrunners dying an early death.

With LiPo in commercial use like the new Evo mounts, one has to take into account not just the wholesale cost of the batteries, but there's liability issues as well. Hopefully the engineering side of it would have taken care with multiple safety redundancies.

That's actually what i like about the 6SE on the stock tripod -- i can pick the whole thing up in one piece and carry it somewhere (usually out to the sidewalk). With a little Starizona LiIon battery back (or equivalent) hooked up to it, it'd be even better. But i often wish i had an 8" OTA i could put on it too when i need a little more power.





Is this the battery pack yo are referring to?

https://starizona.com/acb/batteries.aspx




They currently sell the Starizona II+ model, which i think is a generation or two beyond the original Pinto model. Hopefully it's a bit safer. At least i've read good things about it. But it's all a moot point, because i don't have any money to buy one anyway. I've got my sights set on an Evolution instead.

Does anyone know the verdict on the 8 vs 9.25? It seems like a small increase in aperture...am I missing something? I tried doing some research and I came across a few praising the 9.25 for it's sharpness. Would it really be that noticeable?

I know I want either the 8 or the 9.25 but I want to be informed enough to know if the 9.25 is worth it

The one I picked up last July is this one.

I'd reckon they are probably all from the same, if not similar sources. There isn't any charging instructions; basically plug in, battery pack switch to "on", and charge till the green light switches off. I'm looking to get another pack from a different seller, the ones that are enclosed in a black plastic case.

hmm, on second thot do a search for "18650 12V" - a couple of interesting products using 18650 cells, which should be safer. Not sure about max current draw though.

Did not find any mention of balance charging but a simple controller could be imbedded in the case with access to each cell. A set of swamping resistors and Shottky diodes would also work if the cells were not too mismatched. It would just take a little longer to charge and the case would get warm.

I have been following the discussion regarding the new Evolution scope line and am looking at the 8" model since giving my 6SE to my Navy son & his family up in Washington state. My big concern is the battery and it's replacement when the time comes. I am not a fan of having to send the entire scope or mount back to Celestron just to get the battery replaced. Since I have not seen or heard anything from Celestron about the ability to replace the battery I would assume it is not user replaceable.

If we're going to assume I'd assume just the opposite.
I can't believe that Celestron would produce a product that requires factory Maintenance periodically. How dumb.

I bought their 17Ah power tank 10 years ago, and it is user replaceable (not sure if it was intended by Celestron for it to be so). I replaced the battery 3 times already. Hopefully the Evolution's battery will be self-replaceable too.

Cirrus1500: After owning 2 Celestron 17Ah tanks and having one of them die and not recharge, I contacted Celestron asking if the battery could be changed out and if directions were available to replace the battery. Celestron reps indicated this was not a user option and proper disposal of the battery should be followed. I was very lucky to have seen a discussion on CN that detailed how to take the tank apart and what replacement battery was needed.

hamdul: My concerns regardinding how Celestron would deal with battery issues are based on their previous actions related to my need to replace a dead battery in my 17Ah tank and their lack of support regarding a new replacement battery. So yes, I would assume from the start that the battery would not be a user serviceable item. I will be very happy if they thought this issue through when putting this new scope/mount out into the market. Time will tell if this new scope is a winner.

Nexstar Evolution batteries are projected to last 10 years
They will be replacable by the users
The telescope is made to function at below minus 10 degree Celcius



I can not wait to get my new scope. A Evolution 6 incher. .

I'm new here. also new to telescopes. I was wondering if the celestron nexstar evolution 8 be a good starter scope for me. I've also look at the Omni xlt 120 also the se 152. the nexstar seems to me to be the best choice being since I know nothing it will help me find things other than the moon. I'll be getting one next month on the 4th if opt is open. sorry like I said I'm new don't know where else to ask or post for this.

Chobits,
I have Nexstar 8SE and find it to be a great scope. Of course like all scopes it has it's kinks. The most talked about one is the shakiness of the mount, but I can live with that. You mention that you were considering an Omni XLT 120. I would scratch that in your case. While I love German Equatorial mounts I believe that you'll find it difficult to handle and be able to navigate your way around the sky. You also mention what I believe to be a Nexstar 6SE and while smaller than the 8" would also be a good choice.
As for the Evolution Ah yes the Evolution, I drool every time I see a post regarding one of them. There are several things about them that really grab me. first the gearing. This should reduce a lot of the backlash problems found in the SE series. Next the Lithium battery. This eliminates the use of those Double AA batteries and/or the Power tank and that infernal wire that you have to be so careful of. The alignment procedure using an "I Pad" seems like a breeze. One other point that I'm not sure of is the fact that you can release the gears in altitude thereby being able to balance the tube on the mount and get the balance point more precisely.

oh ya there seems to be so many new perks. ya I tossed the idea of the Omni xlt 120 cause u have to manually navigate, and being new what do I look for after you seen the planets a 100+ times. then I wanted the explorer scientific 152 but I heard it has bad aberrations. also a manual like the Omni. then nexstar "8" seems best of both worlds. with its auto/goto futures also capable of manual if you choose to. love the cellphone/ipad control's I've been to opt telescopes tested that it easy and fun. reachable battery is a perk it seems now where the old 1 had issues. I'm just hoping that the problem has been resolved with the shakiness of the stand. is it more beefier you think the stand? also the worm gears will help to as other say I hope. well I hope ill be happy with my first scope buy. I've done a lot research hope it's not money down the drain

Why? It won't look any different than what you'll see through an equivalent SE or CPC or AVX or CGEM or CGEPro based scope. The standard Celestron SCT optics are the same no matter what mount ... the only time you'll see a change is when you have an EdgeHD ota.

The Evolution will be smoother in operation than the SE, that will make it a better platform for imaging at shorter exposures in alt az mode and with longer exposures in EQ mode. Solar system imaging will be equivalent to a properly setup SE scope. With it's slightly heavier components it should have a little more stability that the SE (seen as less "jittery" when focusing) and with it's better gears should also have a little less backlash (also perceived as smoother operations).

Goto accuracy shouldn't be much different than a well setup SE ... although the Evolution should be a bit less sensitive to a less careful setup.

I haven't used a scope in almost 30 years so I thought I just might ask. thank you for your helpful input. like I said I been doing some research of my own first originally I was looking at the meade 12" dob then the Omni 127 to the explore scientific 152 to thus I've really done my best to explore all options. really don't know what else I can find that will offer me what the evo 8 does for the that price. seems to me it's descent for a beginner scope. I can learn a lot from it

The Evolution series all have an internal power pack that can be recharged directly. No need for an external battery and no more cord wrap.

I would expect the 9.25 to easily handle a 2 inch diagonal and eyepiece. It looks from the photos I have seen that the clearance is fine.

Fred from your experience using the 8"se what do you think I should expect visually wise from the stock ep of the 8" evo 13mm and 40mm ep. don't really see anyone using stock ep on youtube. always seems they are at their best with ethos, nagler, or baader. you have any old youtube video's of your original ep? or something equivalent.

Ok,

Lets look at this from a slightly different angle ...

You won't be able to judge the visual abilities of ANY telescope by asking for videos taken "through the eyepiece". Any imaging done with the scope is completely un representative of what you will see through the eyepiece.

- cameras are generally much more sensitive that our eyes so much fainter objects and color are apparent when a camera is used. Visually every deep space object at this aperture is in b/w. Stars and planets will however show some color.

- when an eyepiece is used with a camera the effective magnification of the image is much much higher than what is seen visually. This is called "afocal projection", it's rarely used but is effective for imaging the planets and other very small objects.

Evaluating a suitable telescope is indeed a daunting task. You're asking the right kinds of questions (just need to modify things a bit). I would suggest asking for other personal experiences with common objects. You should also ask about a the sky conditions when anyone offers those personal experiences ... that will greatly affect what you can expect to see.

Another great source of education is getting some real life experience. Look for folks getting together to view in your area. Try out different scopes and you'll soon have a much better understanding what fits your specific needs. Don't focus too much on the technology of a telescope, it's more about how it will work for you. For example if you are interested in the 8 or 9.25" Evolution (good idea IMHO) then get some time with ANY 8 or 9.25" standard SCT scope (Celestron or Meade). There are some differences with quality of visual images out towards the edges of the field of view if you are looking through one of the modified SCT designs (the Meade ACF or Celestron EdgeHD) but overall any scope in good condition will be an effective comparison.

Also remember that your seeing conditions will affect the quality of your views more than the quality or size of the scope you are using (well within reason). Time spent viewing through other folk's scopes can really help build up the most valuable "accessory" you can get - experience.

Just ignore any images and videos taken through a scope ... they simply won't be like what you'll see visually unless someone has gone to great lengths to make them more representative.

chobits,
I'm not sure what you expect to see on a UTube? Let me say up front I don't believe in taking out a second mortgage on the house in order to buy an eyepiece. Yes I have some Tele Vue's and Brandon's but I bought those while they were still in the price range of mere mortals. I'm not putting those EP's down it's just that their beyond my pocket book and I believe that there are some very good eyepieces out there that won't break the bank. Furthermore I can't understand the rational of spending a zillion dollars on an single eyepiece that has an AFOV of .82 degrees when I can buy a focal reducer that will give me a larger field of view and allow me to use a variety of my existing eyepieces. So now you can't make that statement, "don't really see anyone using stock ep on youtube. always seems they are at their best with ethos, nagler, or baader." cuz now you've met one.
Enough of my soapbox and now to your question. You should expect glorious views especially in the mid range of eyepieces like 15 to 18mm. also using an O-III and/or a UHC filter will blow you away when viewing Planetary Nebulae.

quite enlightening. it's so nice to know I don't have to sell an arm or a leg to achieve a decent view of planets, and Nebulae. I haven't had any opportunity to find someone with a telescope. my wife is blind so I tend to stay home and take of her, and my three year old. so I'm afraid I'm fresh out of luck when it comes to a star party. although a poor choice it seems its all i have why u tube has been my only window of reference till I get one of my own. I did manage to go see the scopes at opt and orange telescopes. scared like hell my wife might take a step backwards or side ways and accidentally knock over one of these 10k+ scopes. with my highly active little one mommy doing her best to hold on to her when she just wants to run and play. all fun but a nightmare at the same time. I'll be checking out those O-III and/or a UHC filters. thanks for all the help hope it isn't such a daunting tedious task helping out your fellow new astronomer...ty Fred, Mark ever so helpful

reasking the question I think I read it some where. but never got an answer. The 9.25 evo does it support a 2" ep? or is there not enough clearance at the zenith.




I've been looking at the 9.25 and it looks like there is enough room for a 2" diagonal. I just have to figure out whether 9.25" aperture is going to be enough to pull in those dim dso's from my orange zone area.

chobits,

You should check out NSN -> Nightskiesnetwork.com Its free to use and you will be surprised to see how much you can see from a light polluted area and a modest telescope using inexpensive video astronomy. Matter of fact you can buy an entry level video astronomy camera for less than $170 or half what a Televue eyepiece costs. The people on NSN are very nice and easy to ask questions too. Give it a try

Al

this scope if I'm correct least I hope doesn't require any of that eq mount adjustments like polar alignment or longitude / latitude. just pointed in the direction of Polaris then your 3 star alignment. but if I got the wedge it would need all those adjustments.

So crossing my fingers this summer.

Oh, need to get the IPad 2 as well. Have the first generation, but can't use the app because of incompatible with the iPad 1.

The Evolution isn't any different than other alt az mounts in the fundamentals of how it works. In alt az mode (no wedge) there is no requirement for polar alignment, the mount doesn't have any EQ orientations (no part of the mount is ever pointed at eq north). You do a two star initial alignment and you're done, one of those stars can be Polaris but it's not absolutely necessary. 3 star alignment is also fine, it's simply used when you don't know the names of the stars ... the alignments have the same accuracy, the 3rd star is only for confirmation of the first two. No matter what mode you use you'll need to have accurate time, date, location, DST, and time zone info loaded. This info is required for the mount/control app to figure out how to initially roughly point to alignment stars and for pointing to solar system objects.

In alt az mode you will always be tracking objects in two axis (tiny steps). The accuracy of the tracking and pointing is totally up to how well you do your initial alignments (choosing the most appropriate stars, accurate centering, backlash mitigation). Alt az mode is however all you'll ever need for visual work.

chobits.
I read the above but for the most part haven't a clue as to what you're saying. Are you using some kinda abbreviations Like they use in texting on the phone? It sounds like you ordered a scope but you never said so in any of your posts. What is "Note 3"? What am I gonna love with the I Pad? What are you waiting for "After the 4th"? I wonder if anyone else is having the same problems with you posts as I am?

Chobist,
Nobody can suggest stars to use on the "Sky Align" alignment because they can't see the stars that you can see.
YOU just look up and pick out 3 BRIGHT stars. Preferably not in a Horizontal row. They should be between 30 degrees and 60 degrees above the horizon.

Sorry Fred didn't mean to confuse you. was just saying congratulations to him for finding the scope he likes, and might get the scope too. I know how fun, and eager he is for I, and him are in the same boat.
note 3 is a cellphone I have that I was able to download software/ap to control the evolution telescope at opt telescope retail store. so I had an opportunity to control it just not look through the ep.
The i pad is a computer/tablet or basically like a huge over sized cellphone with touch screen "keyboard less" or basically looks like my cellphone on steroids lol. where I'm guessing I had fun wirelessly controlling the scope he will too with that giant device.
http://www.samsung.com/us/guide-to-galaxy-smart-devices/galaxy-note-3.html?ci...

I called opt telescope the other day and asked if they be open on the 4th of July cause that be the day i can buy this wonderful scope. they said no they are closed...so my actual day of purchasing/owning this beauty will be the 5th of July.
hope that clears everything up for you Fred thanks again for all your input.

I'll post a link for everyone when I get it

oh skywatcher101 just a heads up when I did go to the store opt telescopes I also told them I was gonna buy the I pad. but they said due the size of it even if you use the red light night mode it will still be to bright. your eye's will have to keep readjusting to the darkness. even dimming your tablet they said won't really work. they said my cellphone was brick borderline. so there are pros and cons to the wireless function I guess. never the less it was still really fun operating it wireless.

It's certainly a tough situation when considering a tablet/phone or laptop for use at a scope. It's something many of us who use video cameras are always dealing with. With video (or any assisted viewing setup) you loose your dark eye adaption because of constantly viewing the monitor. Since the image on the monitor is nice and bright (relatively speaking) this isn't a problem unless you go to also use an eyepiece.

When you are using a scope visually you really do have a problem because you absolutely need dark adapted eyes to really get any kind of effective views of the faint fuzzies. Looking at anything but the most muted red screen will affect your dark adaptation and it takes many minutes of real darkness to recover it. Even the little two line red displays on the hand controllers need to be toned down brightness wise at really dark sites.

For all the gee whiz factor of using a tablet or laptop at a scope the reality of how it affects visual observing is something most folks just don't consider.

when a laptop and camera are hooked up to your telescope don't you get better brighter sharper more color on screen versus though the ep? so hand controlling through your tablet might be a win win for you. since your not using the ep like me most the time. also do you ever feel withdrawals effect of being on laptop to long and want to go back to ep? or are the visuals just that great that you never miss using the ep. I just kinda wonder if u feel you lose realism or the sensation you get viewing through an ep vs always looking at a computer screen. not sure if that makes any since or a worthy debate mark

chobits,

Yup, well aware of eye adaptation. I already have an AP setup, so hooks up to laptop and controll got down packed.

Just really nice to be able to take the scope out, use built in batter power, use iPad or android and away ou go !

Just an easy setup when you have friends and family around and want to show them the amazing objects in the sky. A lot more then little dots in the night sky.

I just got an 8SE and I'm considering returning it for the evolution. My backyard only has a limited 100 degree view of the sky and while I'm happy to view Saturn and Mars, I want to try to see more DSOs. I see the IPAD app as a good thing as it can show me what i have available to me in my 100 degree viewing area. I know all those objects are hidden in the hand control too but the HC doesn't tell me what I can or can't see within my physical viewing limits.

Plus the double slip clutches will be great. I like how low profile the tripod can be retracted so I can fit through my narrow door ways. No more lugging around the battery pack.

Now I wonder if I can return the 8se to hayneedle. I'm still within my 30 days.

Those are very good questions.

You definitely see "more" with an assisted viewing setup (video or imaging cameras used for continuous display of relatively short exposures), but it's different. It has a different feel than sitting quietly at the eyepiece trying hard to pick out details at the limit of your visual ability. For some the technology of assisted viewing is also part of the attraction (for me while I certainly appreciate the technology I also value the simplicity of video).

I also find that video feels more "real" than a pure imaging camera setup. It's a perception thing. To me the eyepiece view is the most real, then short exposure video, and then imaging cameras. Anything that requires that I press buttons on the PC reduces that feel of "realism" to me. I don't have that same problem with turning knobs on a monitor.

I still use eyepieces for lunar, solar and planetary work. My video camera does a good job on those but the eyepiece view is still generally better (I could save a bunch of images and produce better planetary images but for quick real time views I find I prefer my eyepieces). For any deep space objects (DSOs) other than double stars there is no question the video setup offers much more to see. Fainter details and color are all easy with my video camera in any of my scopes.

I have a computer out at my scope, it's there for quite a few functions. It runs a planetarium program so I can look up tons of objects and plan what I'm going view, I also have scope control in a few forms (virtual hand controller and through the planetarium app) so I can look something up and then have the scope go to it without having to find it in the real hand controller and do a goto from there. My video camera is controlled by an app on the PC, I generally just change exposures once the camera is initially setup. I have video display on the PC as well, this is in addition to a video monitor. The video display program allows me to enhance the video image and capture stills or streams of video if required. I occasionally use a browser and look stuff up. Finally I have some autoguiding capability that I might use if I need to use exposures beyond a minute or two (which admittedly doesn't feel too much like near real time assisted viewing anymore), I don't use my autoguider very often. The PC also allows me to run a virtual control capability from another PC in the house, this way I can sit inside and enjoy viewing ... but on nice nights I still prefer to be out with the scope.

Out at the scope the video monitor gets the most use however. It's a CRT model with simple little knobs up front for adjusting the image (something I find you do almost continuously with video). The images on this type of monitor are breathtaking. Smooth colorful images, with great faint details. My LCD PC display can be adjusted to produce brighter images but it always seem a bit coarse to me compared to the CRT display.

Most of the time I use my hand controller to select and goto an object, select an exposure length on the PC, and then just lean over and view things on the video monitor.

I know this was a bit long but I think it's not unusual for any type of assisted viewing. Some folks who use video cameras do everything on the PC, like the folks who use imaging cameras. Some who have video or night vision equipment don't use a PC at all. There are lots of choices for doing all kinds of different viewing.

I use my iPad (retina) every time I observe. I use SkySafari Pro, and between the iPad brightness adjustment and SkySafari brightness adjustment, I don't have issues with dark adaption. I have iPad brightness at the lowest, and SkySafari brightness around 1/2. It is very important, however, to turn off "sleep", and such unless you apply rubylith to the iPad, lest waking it up will blind you.

That said, I don't know how much or if the SkyPortal app has similar night mode (red), and brightness adjustments like SkySafari does...

Took the plunge on a 6" Evolution. I know I'm bucking the odds and I hated being the guinea pig on new high tech equipment, but I ain't getting any younger. It will either be a decent scope or it will drive me to drink . So far so good guys and gals. SkyPortal, wifi control all works good. It's too early to say for sure but I think Celestron may have a winner on its hands.

I just posted a brief writeup in the Show your Nexstar section.

An Evolution doesn't appear to be much of a risk as a new scope.

From what I understand ...

Optics - same
Tripod - same with better spreader
Gears, motors, clutches - same/similar to CPC
Firmware - same core NexStar
Electronics - HC - same, Motor controllers - similar/variation of existing, Wifi - new
Arm, base, covers, clutch control - new

So while there are many new features and capabilities much of the core engineering of the scope is well proven in a number of other product lines. The items that are truly new and unique to the Evolution are very low risk for problems. If I was in the market for a similar scope I wouldn't be very concerned about being an early adopter.

Ramon,

That would appear to be Evan's own scope, so he can post all the pictures of it he likes. Of course if he was still waiting and he posted a Celestron supplied image I guess that would be different.

Mark. Your logic is spot on but I still worry about early adopter syndrome LOL. This is also my first new Celestron since the Chinese took over and I was worried about the quality. I will say that the quality seems to be as good or better than the Celestron of old and I understand that most of the design for the Evolution was still being done in the USA. It will probably all be fine.

Reading all the great discussion on Cloudy Nights about the Evolution help me develop the backbone to take a chance and buy one. I thank everyone for contributing their knowledge and experience to this thread. It does help a person make an informed decision on a telescope purchase.

Pugsx. If you have the option to return the SE and think the Evolution will work better for your application then you should do it before the 30 day return period ends. I have been in that position and regretted not returning something for what I really wanted (or thought I wanted). On the other hand the SE is a proven and well mature design, probably the best all around single arm goto scope on the market. That and the Evolution is almost 50% more $'s. It's a tough call to make. I will mention that if you want to use a computer App like SkyTour, you can always upgrade your SE with Celestron's SkyQ Link WiFi module and get the functionality your looking for.

"ohhh titillating have you taken her out yet??? plz do tell! don't leave us hanging in the dark. and how the heck did you post a picture here? I didn't know you could do that"

Hello Ramon. No not yet. Dam clouds/fog. But like any good "Telescope Nutter" I have been playing with it extensively in the living room enough to get a feel for its function and make wife Inga jealous The Evolution is my newest sweetheart Adding photos and links can all be done in "advanced posts" which you enter by hitting the "preview" when doing a quick response. Hit continue after and it will give you the option to upload a photo. Or you can add a photo URL via "Image" if you have a photo hosting such as Photobucket etc.

Things I like so far:

Very satisfied with the overall quality of the build. I was surprised but in a good way. The drives, optics and software all seem well made/developed & functionally the scope has been performing well in living room tests. The final test will be to see if this scope hits its targets and holds it's position during the night.

The new mount seems much beefier and more importantly rigid. I tapped the scope and jiggled it, the view through the eyepiece settled down quickly and remained steady. Reading the specification for the weight of the mount/tripod, both are more than the SE and I think this weight translates into more metal built into the mount and tripod. The whole setup seems more stable than the SE. Backlash is acceptable and overall gear train seem very precise. When slewing about the motors are about the same loudness as the SE. I also like the new mount having the release clutches builtin. This allows a person to makes quick manual adjustments without using precious battery power. Also good incase you run out of battery charge or your goto craps out in the middle of observing.

Speaking of batteries, I can already tell I'm going to like the built in rechargeable batteries on the Evolution. No more lugging the external 12v battery or using expensive/wasteful disposable. I charged them when I received the scope 4 days ago and have not needed to recharge, despite spending hours slewing the telescope around. So without dealing with battery packs or extension cord and hooking things up, it should make this telescope more convenient to grab and go for a quick viewing session. And as we all know, a convenient scope is a more utilized scope.

Finally SkyPortal. It's a pretty good Astronomy App, free or otherwise. Seems very easy to learn & use. Somewhat intuitive and has enough features without going overboard that most people will be satisfied with it for general viewing. It was asked if it has the "Nighttime mode", night vision red screen function. It does. Sky portal auto adjusts when doing fine slewing adjustments. Very good integration of software and hardware. To me using SkyPortal on a iPad or iPhone is much easier and convenient than using the controller. It walks you through a 1-3 point alignment and then you can go about viewing things from it's Bazillion object database. The entire viewable night sky at your particular location/time is displayed on your smart device. Point and drag, tap on a object and hit the goto button on the screen and the Evolution slews to that highlighted target. However people that are use to Celestron's controller's can always go that route and ease into using SkyPortal. Very flexible in that regard. My wife also likes using her iPhone to remote control the telescope. It add's a bit of "fun gee-whiz" factor and no wires. I'm sure Kids will love using SkyPortal on a smart device so it's a great way of getting kids (or your average civilian for that matter) interested in Astronomy. Make it like a video game LOL. The WiFi range is good. I have tested it from at least 30 ft away and stayed connected no problem. I suspect the range could be even more and that opens the possibilities of controlling your scope remotely from inside the house. Celestron seemed to have thought of most things and covered those bases. I would suggest people download it and play around with it if you haven't already. Also checkout the Video on Youtube that Orange county telescope did, showing a Evo being connected and controlled by a iPad using SkyPortal. Search "Nexstar Evolution" on YouTube.

Clear Sky's everyone, Evan

Here's a closer photo of the other side. I know it doesn't show anything different than what's on Celestron's website, but I alway's like seeing photos of people's actual scopes.

Ha, ha. That's funny. I wonder why someone would post a photo of a scope and claim it it was their's if it wasn't? The 6" was harder to find a couple weeks ago. Most online retailers didn't have them on hand. They had the 8" but no 6 or 9.25" Evolutions. I actually bought mine from Hands on Optics in Damascus Maryland. They where selling them on ebay and had two (they still have one available on ebay). They where the only outfit that had them coming in the mail and could provide a delivery date. June 10th. Everyone else said mid July. Not sure how they got them before everyone else but they did. Price is the same everywhere I looked. $1,199 with free shipping.

Initial charging time was 2 hrs or less. Not sure if that is the typical time. I suspect the battery was partially charged so it may take longer if the battery is run way down.

I just finish installing a Feather touch focuser that I had bought for an SE 8" and it fit my Evolution. The weather looks promising for tonight so I may be able to test the scopes accuracy/tracking and give a report. I think it should perform as advertised based on my preliminary indoor tests. We'll see how it goes.

The picture thing isn't that big a deal. It's only recently that CN has started to be more concerned about the copyright issues. I guess it would be pretty obvious if someone passed off the stock manufacturers images.

Have to say though, Even's pics are awfully good scope shots.

We'll no go on the Evolution test. The clouds rolled in literally right at dusk. I live on a peninsula sticking out into the Pacific ocean and we often get fog or onshore flow. I did manage to get a quasi two star alignment and was able to get one target (M57) in my 19mm Panoptic eyepiece before calling it a night. Was getting dewing anyway. The scope & SkyPortal performed well despite the clouds not making it easy. Today's a gorgeous cloud free day here. Have my fingers crossed for tonight.

Added some better photos in the Show your Nexstar photo thread. Also installed a few accessories that I had left from my previous scope. It seems telescopes come and go more than my accessories LOL.

I don't like the placement of the focuser. Seems like it would bottom out before the diagonal.

I agree but not because of bottoming on the mount base.

The photo is very misleading. There is actually quite a bit of room for longer accessories. I have the tube slid fwd on the rail for balance with about 1.5" of rail left showing aft of the pivot point. It that position there is 2.5" clearance from end of focuser knob to the orange clutch release ring on the base. The Nexstar Evolution arm is much taller which is a nice design change. How much I'm not quite sure but it is noticeable compared to the regular Nexstar. I think this mount is the same for the 8" tube which is over an inch longer and that tube also has more clearance than previously Nexstar's.

No, my main gripe with the focuser knob placement on the 6" tubes is ergonomic. It doesn't feel as natural turning the knob with it below the diagonal/EP as opposed to the right side. It fact it feels awkward. Looking through the EP I keep finding myself reaching for the right side. I suppose it will just take some getting used.

This photo explains it better than my ramblings

Even,

I had the same experience when I put the SCT microfocuser on my C6. You do get used to it but I still find myself occasionally reaching for that non existing knob on the RH side when I haven't been using the scope all the time.

Mark.

Last 3 scopes all had right side focus know location. Muscle memory is hard to change isn't it? Saving for and 8" EdgeHD and that will have a rt side focus so just when I get used to the bottom location I will have a rt side again.

By the way, how did your SCT FeatherFocus fit? I bought mine awhile back for a Nexstar 8SE and the flanged-base of it fit flush in the recess pocket where the orange retaining ring went. I noticed on the 6" Nexstar tube, the recessed pocket seems a tad smaller diameter so the FeatherFocus flange actually sits on top of the pocket. I had to use slightly longer and smaller diameter screws to make it all work. It seems to function fine but was wondering if there are 2 different Feather focuser's for Nexstar SCTs, 6" vs 8"?

Evan,

I can't comment on the 6SE microfocuser setup ... my C6 is a black tube model that came as part of a Advanced series GT mount package and the rear cell and focuser mounting is slightly different than on the SE orange tube otas, but I understand the microfocuser used is the same model.

My bad. I see you did say C6. Have 6SE on the brain. And I see there is only one model SCT micro focuser for the 6SE & 8SE. I wonder if Starlight instruments Feather Touch just fits this way? Oh well it works and I gave it a good test tonight.

Nexstar Evolution tested Successfully.

Just came in from about 3 hours of putting the go-to and tracking accuracy of the Evolution through it's paces. Overall it was a very successful if uneventful test, which is a good thing. I did SkyPortal's simple 3 point SkyAlign which is the default method. After leveling the scope and connecting my iPhone to the Evolution's Wifi network you pick 3 bright stars center them in the eye piece and hit the align button on the screen. One very cool thing about running Skyportal on my iPhone, the GPS coordinates, time of day etc. all that info is fed into SkyPortal to adjust the parameters to your exact location. This info comes from the iPhone itself. No need to input them manually, the software and iPhone do all that automatically. The whole alignment process took all of 5 minuets and considering this was really the first time I used SkyPortal that says volumes about the user friendliness of this software. After alignment is complete you go into the nicely arranged menus for different categories of objects and start hitting your targets. Another neat feature about the objects catalog is it only lets you pick objects that are visible based on your location and time of day. It is very easy to see that an object is not available because the name on the list is de-intensified so you can't pick it. As you scroll through these lists you can see exactly what is and is not visible from your location and time that you are viewing from.

First up was M57. I picked it from the Messier catalogue and off the scope went. When it stopped slewing there was Ring Nebula almost perfectly centered in the 19mm Panoptic. I observed it for about 20 minuets to see if there was any drift in the tracking and was not surprised that it pretty much stayed right where the telescope first placed it. I ran the gauntlet of objects, both deep sky and the visible planets. Even one satellite although I'm not sure if the white speck I saw was actually a satellite or star LOL. In all I had the goto find about 20 objects and it centered all 20 in the eyepiece and never really lost any accuracy. Had some very satisfying views of Saturn tonight. These 6SE optics are pretty darn good compared to my old 8SE. Need to get my higher power eye pieces out next time. I pretty much used a 19mm Panoptic and my new 14mm Delos (nice, nice eyepiece by the way). The wireless interface worked flawlessly. No drops, freezes or other hiccups to spoil the fun. And it was fun using my iPhone to control the Evolution scope. I really like SkyPortal and the whole Nexstar Evolution package. It worked as advertised and I considered Celestron delivered on it's claims. I'm sure that as people get these scopes into the field that issues will popup and I'm sure I may find things as I use the scope more. But considering how complex all this hardware and software is, I am happy that it all seems to work.

Clear Sky's everyone
Evan

I just purchased the 9.25 Evo (which I expect in early Aug). This will be my first scope. I noticed the highest useful magnification on the specs is 555x but the 2nd eyepiece only goes to 180x. I'd like to order another eyepiece or two while I wait for the scope. Any suggestions for a higher magnification eye pieces? Greatly appreciated.

I've got a CPC1100, and have had ONE occasion where I could have used more than 550x. Most nights, I'm topped out under 300x.

Unless you live someplace with supremely good seeing, forget about focusing on super high mag.

The scope comes with a 40mm & 13mm plossl. Those are two useful focal lengths for that scope. I'd complement it with a 24mm widefield, and maybe an 8mm widefield for mid & high mags respectively.

I got a LOT of use out of the 13mm eyepiece in my 11" before I switched to almost pure binoviewer use.

That's going to be a fine beginner scope, but I agree -- it's rare in an SCT when you can use an eyepiece under 10-12mm, except maybe on lunar features. If you can fine a 24mm Panoptic in the classifieds (they show up often) or even afford one new, it is a fine mid-range eyepiece for that scope.

I've seen reviews from folks in the industry but very little from customer feedback like mine. You get some of some of your best feedback (and worst) from ordinary users. Just another info resource on the web to filter and digest. Satisfied with my purchase so far and I think you will be also. Plus, not 100% certain about this but I think the mount is the same between the 6" and 8" which leaves the possibility of installing an 8" tube in the future. The Evolution mount is a great platform for any OTA that is compatible size and weight wise.

I was tired last night and a couple things weren't noted in my initial review but I'll add them now. The goto was as accurate as I have used and in some cases better. I compare (by memory) to my previous GoTo scopes; Meade LX200 8", ETX90, Celestron Ultima 2000 (remember those?) and finally my old reliable Nexstar 8SE. I did a somewhat rushed alignment last night and still the the accuracy was very good. I was using a 19mm eyepiece at 79X and even at that higher power the targets where well within the eyepiece field of view, to the left about 1/3rd the width and slightly low of center. Switching to a 14mm Delos at 107X all objects where comfortably within the field of view after slewing to a target. Through the night I noticed the targets drifting slightly further away from their initial location as the position sensors where building up cumulative errors. This is normal with my previous GoTo drives. The questions is it more or less than comparative GoTo's and can a person live with it? At any point you could always recenter an object and do a realign that would restore your accuracy. I never felt I had to do that and after 3 hours and 20 targets that accuracy was still more than acceptable. Also I expect to get better using SkyPortal and try the other alignment methods to get better accuracy. I'm splitting hairs here. I'm sure most people will be more than satisfied with the Evolutions GoTo abilities. Tracking seems to be close to spot on. After all the slewing about, the tracking would keep the objects in the same position, time after time.

There was one little "oh that's pretty cool" moment. I noticed a red glow illuminating the base of the mount that lit up the RA clutch wheel and tray for your spare eyepieces. It was faint but definitely there so I bent down to get a better look. It turned out to be a dim red LED light that was built into the inside surface of the mount arm and was positioned to shine down on the base to light that area. It was just enough to see the tray where you could put a spare eyepiece or set your glasses. Nice little touch.

Not to much in the way of negative to report. Two things I remember. First in the quiet of the night I could hear every sound coming from the Evolutions drive train. I take back what I said about it being the same noise level as a Nexstar SE. I think it may be a bit louder or maybe it was so quiet it just seemed louder. There was a weird high pitched squeal that perhaps had to do with the clutch. It would come and go. I played around with the tightness of the clutch knobs to see it the sound would go away. It was lessened somewhat when I backed the clutch lock adjustment off a little but never went away totally. Is it just something breaking in, or even a normal sound the gear train makes? I will keep an eye on it to see it turns into an issue. Second. SkyPortal gave me an error message a couple of times when trying to go to an object I know was visible, M31. It wouldn't slew to it. Instead it gave an error message, "object error beyond the mounts limits" or something like that. Not having used SkyPortal before I don't know if this is normal or there's a glitch in the software. Later I tried again with another object very close to M31 and got the same message. Strange. Other than that SkyPortal performance was excellent.

On a side note, a couple new (to me) accessories I tested along with the Evolution. A FeatherTouch Microfocuser and the Tele Vue Delos series eyepiece. I see why people like these two things. The MicroFocuser was an absolute joy to use. I picked mine up a couple years ago at a star party swap meet but just installed and used it on my new Nexstar Evo yesterday. And the Delos 14mm eyepiece. What can I say. The views where fantastic, all the good things we want in an eyepiece. I will compare it to my 10mm Pentax XW when I get a chance and I think it will compare very well.

pjglad - How sturdy is the tripod?




The Tripod appears to be very similar to the 6se & 8se with regards to degree of build. The legs are 1.5" in diameter but the spreader/tray is now a cast aluminum unit. Much more heavy duty than the sheet metal job on the standard Nexstar. It's also lower down from the base which no doubt adds stiffness to the tripod's legs. The base looks different also, thicker perhaps. There are 3 anchoring bolts from below just like my 8SE had. The whole thing feels about half again as heavy when you pick it up. It is reasonably solid, definitely more metal in it. I'm going to say overall it is stiffer and more solid than it's predecessor. The Evolution 8" & 9.25 get Celestron's heavy duty field tripod with the 2" legs.

In the pictures issued by Celestron, the 8" is mounted on the same tripod as the 6", with only the 9.25" mounted on the heavier tripod.

I stand to be corrected.

Hello Ramon. Okay. I measured the thickest part of the leg (where it attaches to the base) on my Evo's scope. It is 1.5" so I'm not sure how High Point is measuring. Is the lower part of the leg where you measure? If so that is about 1 -1.125" diameter not 1.25". I will confess that I probably don't understand the finer points of Tripod ratings LOL. It is a sturdy tripod and offers better stability than the tripod on my 8SE. Going off my "faulty memory", it appears to be slightly thicker, almost certainly heavier.

Pete. You may be correct about the 2" legged heavy tripod only being for the 9.25". I have seen at least 1 photo of the 8" mounted on the heavy tripod, looks to be taken at Celestron's booth at a trade show, however the majority of online photos show it mounted on the smaller tripod. I also read somewhere that the 8" also had the heavier tripods. All this led me to believe (apparently in error) that the 8" had the heavier version.

That is great news actually because I assumed that part of the rather substantial added cost (400 US) of the 8 over the 6 was because of the better tripod. I will be upgrading to the 8" EdgeHD in the future so didn't want to spend the extra $'s on the 8" Evo tube. I realize now that I didn't lose out on the better tripod so thanks much for helping clarify this for me.

Evan

Evan,

I think the 1.25" comment in that description is likely just a typo. You're right, the SE tripod has always been a 1.5" leg model.

It will be interesting to see what C ships for the 8" Evolution.

Adding an 8" EdgeHD ota to your existing Evolution mount will be a nice setup. We'll expect nice pictures of that too (which will probably confuse the heck out of some folks) ... I know you'll get "hey cool scope, where did you get it?, I can't find it on the xxx website". Prepare yourself ...

Evan, Mark,

I had the good fortune to see both the 6" and the 8" evolution scopes at a Astro show I attended with some of my UK friends a few weeks ago.
The 8" was on the smaller (1.50") tripod. The rep at the show told me that it was being delivered to them on the 1.50".
Even with the sturdier mount arm, the 8" still looked and felt under mounted to me. Of coarse, the true test is in using the scope out in the field, something I could not and have not done, so, as they say, looks can be deceptive and the 8" Evolution could turn out to be a lot more stable than the 8se.
I truly hope so as it is a fine looking telescope.

Regards. Peter.

opt telescope shop had the 8 inch edge hd on the vx tripod also the evo tripod. also really easy to remember cause the pearly white vs silver. I was gonna originally buy that setup but they said it be a waste of money for a beginner like me. since I'm not in ap kinda pointless. I'm just looking for casual observation. this is just nother add on to one of many hobbies I do. as many people know me as the hobbyist the irony of getting into this hobby is cause my baby 3 year old popped the questions bout the moon and stars. do to her fascination what better way to show her than through a goto where I don't need to know anything but I can show her everything

I'm guessing you mean the vx eq mount not vb right? whether 6,8" it's fine as far as I know. just have to make sure the dove tail can fit. I'm not for sure that I'm right but, I did look at something like that, but they said the dove tail was different on each it will be the one that's the color orange all I remember. I'm new so I'm guessing 1 dove tail might be for eq, and other alt az. but look virtually the same

Hello all. New to all of this, astronomy and the CN forum, but looking forward to jumping right in. Took delivery from Astronomics of a new Evolution 8 just last week. A "few" growing pains, but hopefully tonight they will be a little less. Too bad that probably won't apply to the information overload my brain is going through.

Love the EV 8's build quality, nice and solid, no disappointments there, just hope I've corrected some screen sensitivity issues between the EV 8 and my iPad Air. Will give it another go tonight.

When we retired and moved to Moab, UT for the blue skies and a relief from the Seattle rain, I had no idea that what is "clear" for Jeeping is a bit different than viewing for astronomy. Still, I think it will be a great place to be looking toward the sky.

FYI, I measured the tubes on the tripod and they are 1.5".

Eventually I would like to get into AP and figure out how to do remote viewing from inside the house (Pipe dream?)

Bill

Glad you are here Moab . . . that is just an excellent first scope that should give you years of good service.

You might also look around in your new area for an astronomy club. They often have their own dark sky observing sites, plus lots of expertise and experience to accelerate your learning curve.

The answer is yes, both the C6 and C8 otas have the regular SCT threads on the rear cell so either size visual back will just thread right on. There is however not a lot of benefit from using 2" accessories on the C6, but if you have them why not use them.

That's the plan. I have to lay low with the wife. She's not to keen on me replacing the "perfectly good OTA" with another more expensive one. Hard to explain the value/logic to her. I might buy a used one as they are coming onto the market and/or sell the 6" first to help finance the Edge 8". I will post pics when I get it cobbled together. As to people asking about the oddball scope? I'm kinda used to it. I've had a couple "Franken" scopes in the past that left people scratching their heads.

I think the Evo mount and tripod are definitely an upgrade to the SE series in terms of stability. There is just allot more metal used and some clever design changes that make the whole setup more rigid. On Celestron's website they list my 6" scope's kit weight at 34.4lbs vs. the 6SE kit weight of 21lbs. The tripod alone for the SE 6/8 weighs 9ish vs 11ish for the Evo 6/8 tripod. I lugged my 8SE around quite a bit and this 6" seems even heavier than I remember the 8SE being. It's heavy.

Remembering and comparing my 8SE, this mount/tripod combination is more stable and wobble free. But it is a single arm mount after all and never will be as stable as a CGE or CPC. My use will mainly be visual from dark sites. I need reasonable portability and am willing to sacrifice some stability in the process. Hopefully when I put the larger 8" tube on this mount it won't turn into the "woblin goblin". I would like to do some limited AP with this setup someday. I think it will suffice as long as I have reasonable expectations. Your not going to get results anywhere near a CGE Pro LOL. That is asking more than the Evolution series can deliver.

Hi Reischbein,

Purely through the associated mathematics; with the 8SE OTA alone weighing ca. 5Kg. and Celestron claiming that its "Total telescope kit" ( 8SE OTA + Mount) weighs ca. 11Kg. then the mount itself must weigh ca. 6Kg.

Based therefore on this, it is further claimed that the Celestron 8 Evolution's "Total telescope kit" weighs ca. 18.5 kg.

Thus assuming the Celestron 8 Evolution's OTA weighs the same as the 8SE's OTA (ca. 5Kg.), then the mount must weigh ca. 13.5Kg.

There is an anomaly though.

The 6SE's "Total telescope kit weight" is claimed to be ca. 9.5Kg. while I believe the 6SE's OTA weighs ca. 3.5Kg. making the 6SE mount 6Kg which would appear to be correct since the 6SE and the 8SE share the same mount.

BUT the Celestron 6 Evolution is claimed to have a "Total telescope kit" weight of ca. 16Kg. which, if its OTA weighs the same as the 6SE, makes the Celestron 6 Evolution mount weigh 16-3.5 Kg = 12.5 Kg. and not 13.5 as one might expect if the same mount were used for both the C6 and C8 Evolution models.

Maybe someone can provide the explanation to this anomaly.

I have not calculated for the 9.25 Evolution model. It's "Total telescope kit" weighs in at ca. 21Kg. but I don't know the weight of the original OTA.

Best regards,
Tel

Evan, glad you are having such great success with your new Evolution. Wish I could say the same. Maybe you or others can offer suggestions.

For the last two nights the alignment process with SkyPortal has been a disaster. I'll be bald by this time next week if this keeps up.

Background, I am running SkyPortal on an iPad Air, 128 GB, no other apps running in the background that I know of. I've followed the instructions for setting up, connecting and alignment.

And it is during alignment the problems start. At first the arrows for changing the telescope's position seem to work just fine, I guess. But as I try to do the alignment, the scope becomes very slow to respond and/or the arrows do not indicate they have been pressed, or there is no response at all. Then sometimes after 5-10 seconds the scope starts moving. Another symptom is when I tap an arrow to tweak the scope to align the StarPointer, the scope moves, tap again it moves, after 3-4 taps the scope just takes off like I was holding down the arrow. Grrrr. This happens time and again. Night before last I spent 90 minutes trying to get aligned, before calling it quits in frustration. Last night was somewhat better, but in the end, not much. I switched to the the NexStar+ control for a little viewing.

This latency is crazy. It is like the program (app) is slow/unable to process the inputs due to processor demand. That seems highly unlikely to me. I also know that mobil devices can experience touch screen issues in cold conditions, but at 75* that wouldn't be the problem. And other than SkyPortal, I've not had latency problems before.

Guess if I can see a star/planet or two tonight I'll give my iPhone 5s a try in the hopes of it working. I just prefer the iPad for the larger screen.

I'm open to ideas or suggestions.

On another note, the FeatherTouch Microfocuser sounds like an ideal upgrade. Especially at higher powers, it seems to me the E's focuser is a little coarse. Like with little detents in the position as the knob is turned.

I read the weight online as 14.8 lbs or 6.7 Kg. Focus Scientific. They list the weight breakdown as follows:

Optical tube weight: 3.25kg (10lbs)
Mount weight: 6.75kg (14.8lbs)
Tripod weight: 5.1kg (11.2lbs)
Total weight: 15.1kg (33.2lbs)

If the optical tube weight is 3.25Kg. then that equals 7.15lbs. not 10lbs. (1Kg = ca. 2.2lbs).

Bill.

The clutch/s didn't loosen did they? I had mine backed off a little two much one time and that caused the scope not to rotate.

Sorry to hear of your difficulties with the Evolution and Skyportal. So far mine has worked almost perfectly, however I only have limited testing so far. I emphasize "limited" having only done the 3-pt Skyalign twice. I agree that it sounds like more of a software vs. hardware glitch. I am using an older iPhone 5 64G so I have less processing power/memory than your iPad. There is almost zero response lag from when I push the arrow button and the scope responds. I think your idea of trying your iPhone is a good place to start. Try it indoors in the comfort of your living room and give it a full test there. If indeed this is a SkyPortal issue then there is allot of info and experience online from users and you should be able to tap into that resource. There are probably some experienced user's on Cloudy Nights that may be able to offer some help. I also hear Celestron is working hard to have good support for the new Evolution line. I would definitely call them and see what they say. I'm sure they are getting an earful from user's having problems and this issue may already be known to them. Luckily you have the hand controller to fall back on.

It's good to hear back from real users, both the good and the bad experiences.

PS I hope you don't go bald. I usually drink when things aren't cooperating myself. Try that instead of hair pulling.

Bill,

On any new SCT you'll hear folks talking about the course focuser feel. Running the focuser through it's full range a few times (hard on the wrist) does help re distribute the lubrication on the threaded focuser rod inside the scope and smooths things a bit.

You do also get used to the speed of the focuser mechanism and with some practice are usually able to focus more accurately. One trick is to run through the focus point a bit turning the knob clockwise and then finishing to the final focus point by turning counter clockwise. This weights the focuser (removing any play from the threads) and the final turns of the knob pushes (rather than pulls) the mirror.

The SCT microfocuser is also a great upgrade ... but I would wait a little while before doing it, you may find that over time the stock setup is working well enough for you.

Evan, clutches are tight, for sure. I've emailed Astronomics again today with the info I posted here this morning, hopefully being a Premier Select Dealer they will have easier access to Celestron for an answer. I also put in a Tech Support request with Celestron. I have yet to come across a phone number for them. And, their chat line is always off-line. Will be interesting to see how quick they respond, especially re a new product.

Mark, thanks for that info. I will definitely give'r a few spins.

Well it could certainly be just a typo or simple math mistake. Another possibility when you see relatively small differences like this in published weights is due to the difference between actual and shipped weights.

The shipping boxes often have the weights pre stamped on them, and some dealers will post those numbers if the vendor hasn't provided anything better. Then the vendor comes along and posts actuals (which are usually a little bit lower because of the weight of the packaging materials) and you end up with two sets of numbers floating around.

SUCCESS !! Just had our first "as advertised" stargazing. The iPhone 5s, SkyPortal and the Evolution 8 worked together exactly as they should. Only took this rookie seven minutes to align and then slew to view Saturn.

Astronomics did contact Celestron who in turn emailed me about the problems. Not surprisingly, they are very interested in getting to the bottom of the issues with the iPad and the SkyPortal app. Sure hope they can push out a fix for the iPad, it is so much easier to read and use. I will post here if I get more info. Kudos to Astronomics for getting Celestron involved.

Now we can start having some fun!

I've got a 9.25" Evo on order. Will see when it shows up.

You know what would be a great feature? If we could slew to the limits of our viewing area and limit all the selections to that particular viewing zone. THAT would be a great feature. I don't want Polaris showing up on the list when it is clearly blocked where I am set up.

just a random question since I'm in to remote control cars. how does the evo stay on one channel and not get controlled or have interference from other devices in the area that might have also the same celestron ap sky portal downloaded on there tablets or cellphones. or can only 1 device be connected at all times? or in memory is it stored as a perm device? since wi-fi isn't it always looking for other devices same as blue tooth and cars?

Ramon, I've been wondering about the same things. A couple of things I would really, really like to be able to do.

1. Use the wired controller in conjunction with the SkyPortal primarily for tweaking the object in the eyepiece after StarPortal has got you there. Quite frankly, I found last night that using the iPhone to control movement is not really all that convenient since you have to look from eyepiece to phone and back. Actually a PITA. Would be nice to use the controller.

2. Remote view, wirelessly, to inside the house especially for those cold winter nights.

ya since its got a distance of some say 20+feet i think u can do that wireless easily from the house Maybe a pc setup next to a open window inside house preferably down stairs. I wish i could remote from my bed room upstairs but i think its beyond its reach. but i have something like a wi-fi extender and wondered if that would work / wifi booster. i used it before for my old x-box 360 to help boost signal to my router upstairs

So you can't have the HC hooked up PLUS use the iphone at the same time?

Actually, you can, but I don't know if the SkyPortal picks up the changes or not. I just assumed it did not. Will require a little testing, maybe tonight.

this I don't know am also puzzled by. I think the combination of a wired device pc / laptop with a seperate wireless device should do it but two wireless I think it shouldn't if does it needs too have option to stop other incoming devices. but then again what do you do at star parties I'm pretty sure they know what they are doing and have a remedy for this. these are all thoughts nothing factual. but things I been wondering since I'll be getting one and wonder how this will affect me directly

just a random question since I'm in to remote control cars. how does the evo stay on one channel and not get controlled or have interference from other devices in the area that might have also the same celestron ap sky portal downloaded on there tablets or cellphones. or can only 1 device be connected at all times? or in memory is it stored as a perm device? since wi-fi isn't it always looking for other devices same as blue tooth and cars?



Ramon,

Very simply, the same way your wifi network is separate from your neighbour's network. This is an intelligent network, not a simple radio broadcast. Remember how you initially setup your tablet device? (choosing the network the scope creates), that connects your device with just your scope.

If you were at a star party with a bunch of Evolutions you would initially see the other networks created by the other scopes (assuming you are close enough to them), but you only choose one of them (yours) and then your device only talks to that scope and vice versa. Your device could certainly be setup to control multiple Evolutions, just not at the same time ... just the same as your device could connect to multiple networks (wifi spots) but only one at a time.

For remote operations (watching images from the scope) have a look in the VEAA and Astronomy Software & Computers forums. There's probably nothing there in terms of active threads but if you search for things like remote control, remote imaging, remote PC, VPN, etc. over the past few years you should find plenty of discussions.

First you have to be able to control the scope (app or connection to the hand controller), this is a low speed fairly simple connection and with the Evolution setup and even easier component. You also need to view though the telescope, this means a sensitive camera and not a planetary camera unless all you want to look at are solar system objects. You need fast exposure capability to be able to find objects (you may be moving the scope around to find a faint object, so waiting longer between exposures is not an option). You also need to ensure that the scope points to objects very accurately (or you'll drive yourself crazy trying to search for the objects), this means the scope must work very well. You'll need to get very good at doing an accurate initial alignment and keeping the scope in sync with the control application. This won't be trivial, you'll need to have some good solid experience with your scope before considering running it remotely.

In general you have two directions to go in (with many different technology options within each).

1) Directly extend the channels to view through and control the telescope to the device you want to view on. Tablets and phones are practically useless at the viewing part except for wireless connectivity (they don't support the required direct connectivity) and there you will usually incur substantial expense and sometimes performance issues (it takes money to do good video streaming over wireless connections). There is the possibility of setting up a hybrid or wired and wireless connectivity. Wireless control of the scope itself and wired connectivity of the display to something like a big screen TV. This hybrid concept could be a good cost effective method since you'll already have the control side take care of.

2) Remote connect to a local PC. Here you dedicate a PC to control the scope, and it's physically located close to the scope. All the traditional connections (USB, serial, video, etc.) are used between the scope/cameras and the local PC. You then run remote viewing software (usually a VPN) on the PC and have it on a good wifi or hard wired Ethernet network. Then you have the other side of the remote viewing software on your viewing and control device (other PC, tablet/phone, etc.). The PC doesn't need to be very powerful so it's a good use of an older PC. The general downside is the performance on the viewing device, it's not like viewing and running things on the local PC, there is a slight lag but if you set it up well the lag is very slight.

slightly OT, but fwiw, R/C has moved away from fixed channels on 27/52/72/75MHz into 2.4GHz spread spectrum (DSM, DSM2, DSMX, DSMR), there's a neat video demo here of a R/C heli with 100 transmitter broadcasting at the same t...

I'm not certain about SkyPortal, but by default it does seem that any device running the app should be able to see a scope's wifi, and there is no password you can setup. But once it's linked, no other device should be able to control it. Wi-Fi is setup to be always 'looking', it's a matter of what devices you've setup in the auto connect list.

fwiw, star parties such as Texas Star Party (and I'd wager it will be the default rule for others soon enough) have a complete ban on standalone (ad-hoc) Wi-Fi and Bluetooth telescope controls, you have to set them up in client configuration (ie, the WiFi Scope has to connect to the general WiFi provided, and you app/program has to connect to same WiFi and control it from there). TSP WiFi rules

Just paced off the range on the Evolution's wi-fi and it worked out to 85'. That is unobstructed, line of sight, no walls, windows or doors to go thru. Maybe tonight I can get a better measurement with a tape. Your experience may vary.

so it's impossible for some random kid in the neighborhood to download the ap to their tablet or cell and try to attempt linking to my telescope cause mines be a one of a kind in the area "easy to find wifi wize" ^^ controlling my scope when I don't want them too? only thought cause it didn't sound like it had a password or anything to block it...cause in anything wifi its an open source hince accessible or hackable by any one i think...plz make me wrong.

ahh ok i think after reading a little more thoroughly once are connect know one can hop in unless you disconnect your device? but that would mean max 1 device is allowed at one time witch is what i thought initially and second device would be hard wired so that would make total 2 devices but like i said only 1 wi-fiable is allows at a time correct? but then again...some 1 can't say link to you and kick you off :P your link? and then assume control?

FYI, I got a reply from a Celestron sales manager about the iPad control issues. He has experienced the same thing and they are looking into it. iPhones and Android devices seem to be OK. He promised to keep me updated.

I have posed some other questions to him, so hopefully I can share that info shortly.

just called celestron technical support and they did confirm someone has ask a similar question I been asking bout the wi-fi and other people connecting to it. and they did confirm YES any 1 can connect to it if they download the ap. and are close enough to it. and also they said there is no password or anything to block it. wi-fi i guess is new to them the concept. so i guess they didn't think about protection. also not much testing in that to where they could answer but they didn't say either about how many or if there was a limit of devices that could actually connect to it. i think if know limit lol it will do till as a pc does it crashes or motor burns out >.< witch what ever soft ware will be bugged or corrupted and very glitchy after that....but they did say if 50+ people called in with this same complaint they would add a fix maybe a update that would install a password should it become a more apparent problem.

With the limited area of coverage (~80' in the clear) the chances of someone messing with your scope are very very remote. In your backyard you're in a position to see someone out in the open and if they are behind a fence or shed or indoors the distance drops off dramatically.

Is it possible for someone to mess with you? Yes. Is it likely? No. Would you pay extra for extra security that you probably will never need? Remember too that a few dollars increase at cost can mean many tens of dollars increase at retail.

I don't think price will increase i think it's just a needed update that can be installed later. just like updating the data base in your remote doesn't cost anything extra. unless newer models come out with upgraded more efficient technical wi-fi system built in I guess you might expect a increase in price. but I really think its a simple update that can be downloaded same place as you can get sky portal from. also served as an optional free add on ap that lets you have a password.

Security is implemented at both ends of a wifi connection, so it would be much more than just software changes to the control app. There would at the very least be firmware changes in the wifi implementation at the scope side. This would require a new hardware revision in the scope and that's $$$. Worse case would be a new chipset and board layout (regression testing, new function testing, new hardware costs, sourcing changes, production changes, documentation changes, etc. etc.), and that's much bigger $$$. Changing a product, no matter how small a change usually means much more cost than most folks realize. It's why vendors don't change their products without good reason (more sales).

Do you think Celestron would make any more money by adding more wifi security to their Evolution line?

Actually I would expect the firmware to be flash or software upgradable for most (expensive) products today. I think it is a reasonable expectation that be available given the good chance that "oops" will happen and they realize a fix is needed. That makes economic sense to me. A lot easier than having to bring product back for a physical fix.

So far, I haven't seen anything in print that would indicate it is possible. Unless, the Aux ports can be use to accomplish that.

Just experimented with using two iPhone 5s' to connect to our Evolution 8. First I connected as usual to the Evolution wi-fi, and connected with the SkyPortal with the first phone. Then connected to the wi-fi with the other phone, started SkyPortal on it, but was unable to control the telescope with that second phone. Only until I closed SkyPortal on the first phone could the second phone control the telescope.

It appears to me after this quick test that the wi-fi connection only responds to one smart device at a time. First come first serve. I did not see an evidence of the second phone kicking the first off. Looks to me that makes the connection pretty secure.

Your results may vary.

I preordered my 9.25 Evo in late April through the Celestron website and was told last week that they aren't shipping them out until late July and to expect them mid August. Where you told something different? Did you order from another site? Just curious.

It was pretty cool. It was nice that they showed me the app then let me install and control it. Great way to sell a scope. But ya next week on Thursday I'll be going to the store to pick one up

Where did you pre-order it from since celestron does't take orders directly? I found that out month ago when I had asked bout the omni Xlt 120. Also my local store can get a scope from celestron bout 3 days. When I asked bout the 9.25 they said that wouldn't be available till last week of June-first week July for purchase. Oh funny forgot to mention the YouTube video done by Mike at oc telescopes he is the other retailer store I fail to mention besides obt telescopes that I actually talk to personally. Cool guy knows a lot to bout scopes.

Hayneedle.com. If you check one out, they list expected shipping dates along with various cost options. I have not spoken to them so I'm just going off their website. It seems to be that if you choose the $125 shipping option that gets you the package in 3 or 4 days, they should deliver, no?

Bill,

You're not dealing with a highly integrated device like a phone or tablet, your scope is made up of a variety of pieces. Parts of it are flash upgradeable and other parts may not be. Would you pay more and wait longer for the development of a product that is completely upgradeable?

Goto telescopes are obviously not produced at the scale of a phone or similar consumer electronics, and the companies behind them don't have anywhere near the same resources and reach. They are usually built on technology and components well proven from previous product generations, so they aren't net new on each iteration. It would probably be good to accept that there will be differences in the way these products are handled compared to mainstream consumer electronics ... and not every expectation can be met.

Mark, I understand what you are saying. You, and almost everyone on CN, are way more knowledgeable about astronomy and the hardware than me. That said....

Those of us who have purchased the new Evolution have already paid more for the technology. Wi-fi and SkyPortal as well as some hardware improvements over the SE Go-to SCT. I have not found any documentation which says that any part of the product is flash upgradeable. Yet Celestron put four Aux ports on the mount. Why they didn't take one of those and incorporate flash upgradability, is a mystery to me. Just look at SkyPortal. It has a smart device issue. Now what if it wasn't fixable. The Evolution product line would be no different than the SE Go-to SCT. But, it is fixable and when they get an update we will all just download it and be good to go. Yes, they are spending more money to fix and/or improve the app, but when a company markets this technology, the consumer has a right to expect it to be right or fixed/fixable and the company would know this for their pricing structure.

Hopefully all this is a mute issue with the firmware in the mount and it will be fine. But if not, what then? Who knows, maybe the whole thing is bullet proof.

This will warm the cockles of your heart. I just got a reply from Celestron Tech Support answering my question regarding the problems I've described with the iPad and SkyPort. Their answer was to change the rate button on the app. Completely ignoring the described issue and what is now a known issue to Celestron. I'll cut them some slack, it has only been a 2-3 days since this became public knowledge, right?

I just love that im the new guy don't even have a telescope yet and im baffling them >.> they seem to me everyday questions...I guess

You can update the hand controller firmware, motor controller firmware, and the SkyPortal app for sure.

Great! Understand about the app. Where can I read about hand and motor firmware upgradability? I don't see it in the Instruction manual.

App Database
Over 120,000 including 220 of the best deep sky and solar system objects

does the hand controller and sky portal come already with all 120k+ objects? or do you have to update that to get them all?

Ok, I found on the website the product description of the NexStar+ Hand Control is flash upgradable.

Still searching for the motor controller info.

Ramon, I think the hand controller "only" has the 40,000.

Right you are. My eyes sure missed those four words..."and updating firmware via PC". Wonder if that also covers the both the NexStar+ Control and the motor control.

Thanks for pointing that out.

In the market for new ep...
ok probably nother horrible question. but I don't know enough to ask right sorry...I heard people say galaxies are good to look at through a 33-40mm ep. planetary around 25-15mm? lunar 10-5mm? if I'm wrong plz correct me or put it in a context I'll understand. scope comes with a 40mm and a 14.5 mm if I remember. if I wanted to say see nebulae like M57, M42/M25 what mm would I use? with the evo 8 inch. or the NGC5005 or NGC6503. what EP should I use?

Those of us who have purchased the new Evolution have already paid more for the technology. Wi-fi and SkyPortal as well as some hardware improvements over the SE Go-to SCT. I have not found any documentation which says that any part of the product is flash upgradeable. Yet Celestron put four Aux ports on the mount. Why they didn't take one of those and incorporate flash upgradability, is a mystery to me. Just look at SkyPortal. It has a smart device issue. Now what if it wasn't fixable. The Evolution product line would be no different than the SE Go-to SCT. But, it is fixable and when they get an update we will all just download it and be good to go. Yes, they are spending more money to fix and/or improve the app, but when a company markets this technology, the consumer has a right to expect it to be right or fixed/fixable and the company would know this for their pricing structure.



Bill,

As you've already heard the HC (hand controller) and MCs (motor controllers) are flash upgradable. The HC (with it's NexStar firmware) is the brains of your mount, the motor controllers (or anything else inside the base of the mount) don't have much in the way of smarts. Electronics wise your scope is almost identical to an SE or CPC scope with the addition of the wifi module.

What Celestron calls an "AUX port" probably isn't what you expect it to be. The HC, MCs, wifi, GPS, and some other external options like StarSense all communicate together via a common bus. The AUX ports are ttl level connections to that bus. They aren't buffered or protected so you can do real damage to the electronics if you try and connect them to anything that isn't ttl compatible (max +5v, or draw too much load for example). On other mounts all the AUX ports are electrically identical, they are all connected to the same point within the mount. The Evolution is likely the same.

The other similar Celestron mounts have 2 AUX ports and a HC port, those are all the same. So on an Evolution it appears what Celestron has done is rename the HC port as one of the AUX ports and add an additional AUX port likely because of things like StarSense (along with any other potential add ons they might have planned).

Treat the AUX ports as extensions of the internal communications of the mount, and the only things that should be plugged into them are Celestron approved devices (some folks have certainly done their own work to add items but by in large you don't want to be messing with these ports).

The normal method of connecting to the external world for communicating with the electronics of the mount for things like flash upgrades, connectivity to other PC planetarium apps, or autoguiding is via the RS232 serial port on the bottom of the HC (it's a small 4 pin RJ22 connector). Before the built in wifi showed up on the Evolution mounts the way folks did any wireless connectivity was to connect an external wifi to RS232 adapter to this port.

Perhaps in the future Celestron will open up the specs for talking to the internal wifi in the Evolution but until that happens any connectivity has got to go through that RS232 serial connection and not those AUX ports. The really good news is that there are tons of well proven apps that will work with the Evolution because it uses the same well proven NexStar firmware as most other Celestron scopes/mounts.

Ramon,

It's really not a matter of one eyepiece for a certain type of object. It's more about matching the eyepiece to the size of the object.

The choice of eyepieces is a very personal one, in addition to the focal length you also need to consider the eye relief (how far away your eye will be from the top lens surface), the apparent fov (how wide a fov the eyepiece will create, this is also determined by the design of the eyepiece), and in some cases the exit pupil.

25-40mm are usually considered wide field of view (fov) eyepieces best suited for big objects like extended nebula such as M42, M17, etc. You can usually also see the whole lunar disk with one of these eyepieces.
Below that are mid range eyepieces, usually in the 13-20mm range. These are likely going to be your most used eyepieces. Here you'll be viewing most deep space objects, lunar views, and sometimes the planets when for example you want to see some of the moons of Saturn or Jupiter.
Down under 12mm or so are the higher power eyepieces mostly used for planetary work or viewing small DSOs (like small galaxies, tight double stars or small planetary nebula).

Only on those very rare good stable nights will you likely ever use really high power eyepieces in the sub 6mm range.

These are general ranges, and some folks may quibble about where the ranges start and stop, but that's really just an academic discussion. You can easily just start off with one eyepiece in each of the low power, medium power, and high power ranges. The choice of the type of eyepiece is dictated by your budget and viewing preferences. I find comfort wise that in general eyepieces in the 68 range work best for me, but I also very often use an 82 13mm Nagler T6 in my scopes.

Don't sweat the variety of choices, it's actually hard to find a really bad eyepiece these days. Your best bet is to see what others are using and if possible try them out to see what you like (star parties run by your local astronomy clubs are very helpful for this).

If I were you I would probably just look for a reasonable 8-10mm eyepiece for planetary work. Then just use what you've got for a while, try out some others and then later on see if you want to buy something else.

Wow Mark. Thanks for all of that great info. Based on what you wrote, especially in regards to the technology, I have to question the value of the Evolution series. I only hope that the mechanical and build improvements will justify the cost over an 8" SE Go-to. While I like the wi-fi/app, controlling is much better with the HC.

That is exactly the real justification.
The upgraded gears... worm vs spur gears is a nice upgrade.
The clearance between the visual back and the mount is a big upgrade.
The fact that the scope can be moved manually in AZ is a huge upgrade imo.

ty very much mark always a BIG help. thanks for taking the time to explain. I did think for abit about this and seems I did good cause I was close to what you said between 7mm-10mm. seems we are on the same page I been trying to rea lately what might be available to me to see n my general light polluted area. and trying to take down list of objects I guess to try to see later. I have no idea what to really expect but I am eagerly waiting in anticipation to what there is to come. your options are now added to my growing list of thing to look for the M42, M17 and moons of Jupiter and Saturn. check, check, check....ty

ya I thought the evo came with a bunch load of new upgrades even small meniscal upgrades not really mentioned but still upgraded.
(1)Wi-Fi,
(2)worm gears,
(3)both Alt-Azimuth - GoTo,
(4)the extra height difference for the arm to add a 2 inch ep
(5) etching in the tripod steel legs help aid the adjustment of the bubble level to help balance the scope accurately. lol thats 2 things there :P
(6)better tray holder top and bottom, adds a little to stability/rigidity of mount
(7)adjustable aluminated red lights for ep tray and celestron logo can also be adjust through wi-fi device!
(8)rechargeable battery pack of 10 hour times
(9)focuser mike said from oc telescope he said it even feels they changed the insides of that to role more smooth and make it easier to find a more fine focus
(10)improved the Optical Coatings to the StarBright XLT maybe the eye can't detect the difference but its still there

boy I feel I should be working for celestron... I just got through promoting for them lol I know half sayed might not be worth mentioning but for me its been my check list and I like it a lot! worth every penny ^^ every upgrade

kinda sorta the way I say it its not even a se any more its a whole new scope
oh wait I think I now know why they call it the evolution...lol

Bill,

What jhighfield said.

Just simply think of the Evolution as the SE crossed with the CPC series. The ease of use (less weight and simplicity) of the SE, with the precision, smoothness and most of the robustness of the CPC, the great proven NexStar firmware from both, and then with the addition of wifi and the cool control app. I think the Evolution is a great value.

(11)and last but not least...one of the main reasons why I like this scope the most, is the future that lets you "save" your 3 star alignment so every time you turn it on it is ready to go instantly at the turn of a switch. unless you travel I think 15 miles away from your last present location would it require a new star alignment.




Um, no. You can hibernate any NexStar scope and it'll remember the alignment. However, if you move it at all, you need to re-align it.

ok I see my error I did a few phone calls and had it tested. basically if u have an observatory like setup where your scope doesn't move then hibernate then that future will work 3 star alignment will no longer be necessary. but if you do move your scope it will need a new 3 star alignment. I miss interpreted what mike from oc telescopes said. a lot info to process lol still great future non of the less. and I'm guessing what 5 min or less procedure :P cake walk

Alignment is roughly 5 minutes if you do SkyAlign. It's really quite painless as long as you use 3 very bright stars. It is best to start alignment when you can only see very few stars, that way you're sure to pick ones that will work without issues.

Shoot for stars between 30-60 degrees in elevation, and at least 90 degrees apart in azimuth for the best results. Try not to use planets or the moon, even though they will work.

My suggestion was for SkyAlign. Before I got my StarSense, I had much better luck with Auto 2 Star alignment, where I'd choose Polaris as my first star, then toggle through the next choices to find a star a long ways away and at a decent elevation, and the scope would slew to the vicinity and I'd center the 2nd star. SkyAlign & Auto 2 Star give the same accuracy, but 2 star is faster as long as you are sure of which stars you're using.

Fred,

The pros:
Aligns before I easily see stars with the naked eye (when the brightest stars are just visible in the blue sky, the SSA can align).
With latest beta firmware, goto is very good on everything.
Alignment takes about 3 minutes with no intervention (with a non-GPS scope, you'd have to verify time and possibly location before it aligns by itself).
Plays nice with SkySafari plus & pro, so the con below regarding the menu layout is not a big deal.

The cons:
No All-Star Polar Align for EQ mounts (wedge or GEM; expected to be fixed "soon").
$330 price tag.
NexStar+ menu layout (I prefer the V4 layout).
Mounting shoe & camera are heavy enough I had to add more counterweight on my scope.
More wires hooked into the mount that could catch on something without good wire management.
As of this time, the SkyPortal App will not work with the SSA camera, so Evolution mount owners who go with a StarSense would need to use the StarSense hand controller for the immediate future instead of the app.
