Which CPC?
      #5796845 - 04/13/13 03:37 PM

I'm trying to settle on a single main scope and having tried various sizes from 3" to 8" of SCT's from the Celestron and Meade stable I'm drawn once again to the CPC range.

This scope will certainly be used for 90% visual work but with the idea that a little AP might come into the mix in the future.

I view from my garden and as such have a level of LP to contend with. I'm also based in the UK so seeing is never particularly great.


Anyway, in a effort to finally settle on a scope and whilst I'm still young enough not to worry about the weight I thought I could get the CPC1100, aperture rules after all?

However, with the ever growing reputation of the Edge series though is it worth considering a smaller Edge version? For example the 9.25 Edge? It suggests an updated fork mount as well and has the vents and mirror lock?


If I consider average "seeing" though are these sizes overkill and I should simply stick with the 8" like I've used in the past?

Any advice would really be appreciated as I've gone round in circles too often and I'd really like to think that this purchase is going to last for many years to come?

Many thanks,

Hey seico! If you are still deciding, then I suggest google search 'review cloudy nights CPC " and enter various inputs like 800, 9.25, 1100 and also these values with "vs".

I'm using my phone right now : ( or I'd try and find the link that shows a general comparison review of these models or of these vs edge hd. I found it very useful info, but still went with what I could find used in my budget : )

You might check the classifieds here as I think there are a few cpc 1100 for sale.

Sorry I can't be more helpful.

It would be hard to imagine a better visual scope than an Edge HD based CPC. The alt az setup is very simple and comfortable to use and the optics are simply some of the best ever in an SCT.

One thing you need to balance against "aperture rules" is the weight of the of scope and how easy it is to setup. Your viewing environment will dictate some of the restrictions (any stairs, do you have to lift it, how far to carry the scope, can it be left setup and on wheels, etc?). Don't dismiss the additional weight of the 9.25 and 1100 scopes, they are a lot to lug around ... especially in the dark. While you can see more with a larger aperture scope it's no match for a smaller scope that gets used more often.

Could not agree more. I like my CPC1000 HD but the 8SE sees more use. The big fella takes some commitment in time and energy and I am sorely lacking both after a long day. The CPC 1100 has become a "special conditions" scope and I'm fine with that. Having both scopes on hand is a wonderful luxury.

I think the 9.25 edge CPC would be the perfect answer to your stated desires, with the potential for wedge-mounted AP down the road.

Thanks,

Well it's down to three,

CPC 1100
CPC 1100 deluxe

Outside chance
CPC 9.25 deluxe

I am really drawn to the 11 as I think it's now or never to get a scope that size. Thankfully it can sit in the conservatory and will only need to be carried a maximum of 12 ft for viewing. Only problem is the price of the HD version is 2K more than the regular? The regular CPC is clearly the best bang for the buck is a relatively old design now.

If at all possible handle a large SCT (NexStar GPS or CPC 9.25/1100) before you buy. Take it apart/set it up and be sure you can comfortably handle the scope. There isn't much difference in the weight between the 9.25 and 1100 scopes.

Here's a big thing to know: a C11 on a CPC 1100 mount: 65 lbs. Thats a lot. It's a heck of a lot when you have to negotiate doors and move outside. It's heavy combined with clumsy and fragile. Then if you want to go on a wedge- that gets scary (I've done it a lot).

However, if you take the C11 off the forks, now it weighs 25lbs and is just a large paint bucket to move around, and is very easy in comparison. Likewise, a gem mount head is compact and fairly rugged, so it is much easier to move.

But in food for thought, a gem mounted C8 is only 15 lbs and very easy to move, and mine has always given better views than the C11. They both started out on forks. Neither is, today.

thanks Rich,

I have an Edge HD 8 already and really did consider a GEM mount. I just cant see myself messing around with one though. I looked at the Sky-Watcher AZ-EQ6GT so I could at least use it in Alt Az mode but that's a chunk of money so I kind of arrived back at the CPC for sheer convenience.

Other that the cost I really like the look of the CPC1100 Deluxe HD.

I would have settled for a standard CPC1100 but everyone is buying into the Edge marketing so it looks like I have a dilemma on my hands?

I had the CPC-800 but ended up going the GEM route mainly for imaging, but also to save weight. I have a bad back and just lifting the CPC-800 was a task. I now have more lighter parts. The heaviest part is the mount head at 29LBS.

I think you've already been sufficiently warned about the weight of the CPC-1100. Nobody can tell you what you can handle, but yourself.

The only thing I'll add is that the Edge is worth it in my opinion.

Thanks Adam,

I had the CPC800 and got rid of it as I'd just come from a Nexstar 8i so visually I'd gained nothing. I used to carry the CPC800 downstairs and then outside and could manage. I appreciate the CPC1100 is much heavier however it only has to be carried out from the conservatory to the garden.

I'm just struggling with the price at the moment. 4k on a scope is a lot of money (for me at least) and I have no idea what to expect from the visual improvement over the 8.

Just a mention regarding lugging an 1100CPC Edge around.... Read the post dealing with the "$60 storage case". I wheel my 1100CPC Edge everywhere in the wheeled storage box. My only lift is to mount it on the tripod. As long as you are not negotiating stairs, the box solves most of the weight issues associated with 11" CPC's.

Best of Luck

You views will improve noticeably over the C8. A bit more of everything. You won't be bowled over. It is a bigger scope and DSO's really start to show. In steady skies the planets are all more detailed. Is that improvement worth $4000.00? That's a tough one!

Yes, exactly that is a tough one but I do need a main scope as the little N5i is too small and I miss the bright views of globulars etc. I'm just weighing up what to get really.


CPC 1100 Edge (The big one, in every way, would be the best I'd certainly ever likely to own or need but what happens when the CPC Ultimate is released in a few years that has QUIET slewing. (Are you listening Celestron). Also, its a bulky unit and I don't believe people are exaggerating one bit about the weight and dragging it out at night! The cool down times might prevent a lot of use too as I'd have to set it up pretty quickly at the start of the night to get any use out of it at all. Of course, active cooling fans can be bought but that's even MORE expense.


CPC 1100 (Big but doesn't break the bank but how will I feel after a month or two knowing it's not the Edge, doesn't have cooling vents, mirror lock etc). It's still a chunk of money and I don't want it to feel like a compromise). It still has the cooling issues and weight issues that might mean it doesn't get used as much as a primary scope should!

CPC 9.25, CPC 9.25 Edge - I see no advantage to this one, too close in size/weight, very similar to the 8 visually and not much cheaper than the 1100? This would feel like an incremental upgrade to my 8's in the past.

CPC 800, CPC Edge - The baby of the bunch and having already previously owned the CPC800 I know what to expect. The cash saved compared to the 1100 would be 2K on Edge alone never mind the standard version, allowing me to buy all those lovely accessories, eyepieces etc.

So, yes, it's a dilemma. If I had a chance to view the 1100 in person here in the UK it would be so much easier.



So I guess another question...

Two choices as they are at the same price point...

Standard CPC 1100 or CPC 800 Edge?

Improving views over a well tuned edge HD C8 is pretty hard. Meanwhile, usage is inversely proportional to the square of the mass. CPC1100s need time and a buried needle on the motivometer to get it out the door. In my own case, I have a C11 which has yet to show anything visually from the city I couldn't see in the C8. All it does on planets is push another 40% magnification I can't use, while making it impossible to get objects like the double cluster in one field.

I'd agree with what Rich said......look, it's a tough question to answer.

You can always buy what you are most interested in and return it if it doesn't meet expectations. You'll be out a fair bit of coin on the re-stocking fee. There is no free lunch although I can recommend the tuna salad.

Good luck!

Hi,

I've just been down this path and ended up buying a CPC 1100. Why?

Aperture, I live in central Melbourne Australia, 4 million people and lots of light pollution. Put it next to my 8 inch newt and I can see heaps more despite the light pollution. I don't look at the edge of the field, so a small bit of field curvature doesn't bother me. There is a lot less than I expected - though I'm only using Hyperions with a 68 deg field. Dont miss vents - remember hthe edge needs them as it has no way for hot air to escape otherwise. I just stick my scope out with its bum in the air for a while and it cools fine. I have to carry it up a flight of stairs to view, and at 61 yo I can do it without problem - I'm not built like a footballer either! Imaging? at 2.8 meters focal length? get a PMX or similar. I'll just put a refractor on top and use that. or do some planetary webcam stuff. Lovely scope and I am exceedingly happy - the optics are stunning. Had my best ever view of Saturn 2 weeks ago at 400x...blew me away.

FWIW
cheers
Gary

I think Gary from Down Under makes some good sense. I picked up a CPC 1100 on eBay last summer after a decade with a Celestar 8. LOTS of bang for the buck. I'm not trying to compete with Jason Ware and the Hubble for photos, just want to have a little fun and capture my own. Plus 80% of the time I just want to put faint objects millions of light years away on my very own eyeballs. From my deck in downtown Boulder CO, the GoTo is wonderful!!! Even though I can't see all that many stars towards town, I can still find and see many deep sky objects with the GoTo. We don't get many nights of good seeing, being smack up against the mountains here... but on the rare good seeing night, or on a weekend trip to Utah... Saturn, the moon and Jupiter are amazing.

I'm enjoying my 1100!!

I actually have both the cpc1100 and older celestar C8, just like Jim. I have set my cpc1100 outside with a telegizmo cover. I use it as my main imaging scope, my C8 I use as my travel scope.

Like Jim I suggest you try and buy used. You can often get very good deals and save enough for a second scope,,this way you can have a primary larger and less moveable setup and then have a smaller and more mobile scope/mount combination. For the price of a brand new CPC1100'standard or edge you can get two setups used...

Just my 2c

thanks, I normally buy used the only exception to that rule has been my ETX90 EC many years ago. I quickly found buying used saves me a good 3rd.

Alas, I have yet to see a CPC Deluxe come up for sale. I missed an "as new" standard CPC9.25 a few motnhs ago because I had decided on an Edge 8HD and Nextar mount as my grab and go. The new Nextar SE mounts are awful though compared to my 5i (noisier and slower) so I've had to rethink.

Weirdly, accepting a CPC actually means its going to be even slower and noisier but at least it is stable!

So yes, if I can find a used Deluxe I'll grab it or a larger standard CPC at the right price.

The CPC should be quieter. They're essentially silent when tracking and pretty quiet when maneuvering. The older NexStar GPS scopes are extremely quiet overall, though they are also slower.

If you are buying used, and Edge is not critical to you, I encourage you to consider the Nexstar GPS series.

I have recently owned a CPC 800 and a Nexstar 8 GPS. The optics in both were comparible. After that the Nexstar GPS was far superior. Better tracking, much quieter, no cord wrap to fool with, etc....

I would really love to figure a way to mount my Edge on my NExstar 8 GPS mount...

They can be had pretty cheap too. I got my Nexstar 8 GPS with JMI case for $875.

While sold, here is an exammple:

Yes, thanks, I actually like the nexstar 8 GPS and can quite believe they're much quieter. It's such a shame Celestron switched to awfully noisy motors or slightly misaligned components creating a racket when slewing. Wouldn't mind they even had to cut the speed!

I opted for the less expensive CPC1100 (non-Edge) because I knew most of my imaging would be with the Hyperstar. There is no optical advantage of the Edge over a plain CPC1100 when in Hyperstar mode.

As for cooling and temp equalization, I purchased an SCT cooler. Works just fine.

For those good-seeing windows where I want to image in non-hyperstar mode, I purchased an SCT Corrector from Starazonia ($349). It works great! Flat field - Edge like images from the CPC1100.

The CPC1100 is a beast. Mine stays on a tripod with retractable wheels. If I had to mount it every time I used it....well, I would/could not use it.

thanks for the response Katie, and yes the regular CPC1100 looks like a fantastic scope for the price. I'm just struggling to pull the trigger on it because lots of people suggested the Edge. Deep down I know I want the Edge version but its a little over my budget. If I can find a good deal then I'll get the Edge version but if I cant then I might fall back to the standard CPC. Weirdly, we ALL know that for visual the standard CPC1100 will be stunning but for some reason the Edge marketing team have us all spooked about the edge of field flatness!

Oh and alas, I'll have to set mine up each time although thankfully not so far. 15 feet or so?

My attitude about field flatness for visual use is that on stellar and small width objects (looking at star color, double-stars, planets, small globulars, small galaxies) your concentration is on the center of the view and only use the periphery as context. Slight curvature on the edges doesn't matter.

On extended diffuse objects (nebula, galaxies), where you let your eye roam around the field of view to enjoy the details across the object, curvature is more complexly rendered and not even noticeable. Again, slight curvature doesn't matter.

Maybe, just maybe, on a large globular might there be room for curvature affecting the stars on the periphery... but once again, your concentration is more on the center where it is undetectable. Slight curvature doesn't matter.

For visual use, in my opinion, it is more of an intellectual argument of specs than it is a determent from pleasure. Slight curvature doesn't matter.

Also, the edge scopes are too new and too few available for there to be many used deals. They would get close to list price (plus your shipping) on any market.

Caveat: I have a Celestar 8 and CPC-1100. I have looked through an Edge only 8 one time... it was a great view. But then again, I was getting great views in my scope that night too. With different eyepieces etc, nothing jumped out at me in the Edge scope and difficult to compare!! And I paid less for my ebay 1100 than he paid for his new 800 Edge. ;-)

My 1.5 cents. Oh, did I mention that slight curvature doesn't matter?

thanks Jim, you know I know you're right too. I think its also a bit of an ego thing too! It shouldn't be but that NEWER model is irking me?! I can get the Deluxe for less than 4K (my limit) but only from one source. Only problem with the source, it would be an import and I dread the thought of a problem rearing its head needing me to ship it back to the retailer!

They never make it easy do they? Even if I can grab my so called bargain at <4K for the Deluxe I still think the 2.5K standard CPC is a fantastic deal!!

To the above, allow me to add another decision point (as if you did not have enough already).

When I went looking, specifically for the CPC1100, I did the normal on-line shopping and comparison. But, when it came time to actually purchase I went to the nearest Celestron dealer and cut a deal...not that far north of the on-line prices.

I picked the local purchase option for three reasons.
1) The folks are very nice and provide free support(already had that one come in handy a week after purchase - replaced the cover at no charge).
2) No ship back to Celestron for repair.
3) It is good to support your local dealer (IMHO).

This beast arrives in two boxes. The OTA and fork are in a box 36x19x30 inches. The tripod is boxed at 36x19x16 inches.

I can not imagine man(girl)-handling a 70lb box to ship to a dealer or Celestron.

Have we mentioned that slight curvature doesn't matter?

I have viewed the same objects, often using the same eyepieces, on the same night through my standard CPC1100 and our club C14 Edge and the only visual differences I have seen were attributable to the extra aperture, not the comparative design. I am convinced that what goes on outside the scope -- seeing, transparency, light pollution -- has a much greater impact on visual observing than the optical design, aperture and good collimation being equal.

Best bet is that when Celestron engineers sat down to design the Edge they had imagers in mind far more than visual observers.

It has been but there are clearly 2 camps even on cloudy nights. I thought that I'd be laughed at for even thinking of getting the Edge for mostly visual but a lot of folks suggest to get the Edge as it is much better when wide angle eyepieces are thrown in the mix?

Someone mentioned "slight curvature doesn't matter" once or twice earlier in the thread. I think. ;-)

I live up against the Rocky Mountains in Boulder, CO. Which blesses us with gorgeous views, lots of blue sky days, no humidity, clear skies... and terrible seeing. Spectacular clear, dark nights often harbor all kinds of turbulent air that you can't see... until you peel off the cover of your scope.

For the first few months I had my CPC 1100, while I was excited about the deep sky objects I could see... it was all I could do to imagine a single cloud stripe on Jupiter.

Then... I drove out to Utah. Holy Mackeral! I thought I had a new telescope. I could see martians that had landed on Jupiter. I could see the Apollo 11 flag standing on the moon. Well, not quite.

But the difference was amazing. Even the Edge optics can't do anything about poor seeing conditions or loads of humidity and bad transparency.

Good point, Mike!

Jim

Thanks Jim, yes, weirdly, that's another reason I'm pausing for thought. Coming from using C8's I certainly hope the C11 will give me a notable increase

Good luck with whatever CPC model you go with!
I was looking to get a Nexstar 8SE and had posted that in the Nexstar forum but took your suggestion and have decided to go with a CPC Edge 800. Having had the 9.25 non Edge version yrs ago I know the mount is pretty solid but the 9.25 could be a pain sometimes as far as being portable.
I think the CPC Edge 800 will be good for me as I'm looking for portability and a stable mount and at only 43 lbs for the OTA and mount it will be easier to move around:)
Celestron claims they have made improvements to the mount and drive section..anyone experience improvements there?
I know my old CPC 9.25 was pretty good..even on 1 star allign it tracked quite well and was fairly quiet.
Just going to use the beast for purely visual!Should work well with a nice set of Brandon eyepieces I got last yr!

Many of you wrote about how heavy the CPC1100 is. I am quite sure it is. What about having a CPC1100 in something like a scopebuggy? I am planning replacing my CPC800 with the 1100 (for observing). I will have to push the CPC1100 on the buggy for about 20 feet. Can anyone comment on that?

Hi Fernando-

It all depends on the surface you are wheeling the CPC1100 across. I used to keep my CPC1100 in the garage and all i needed was to wheel it out about 10ft on the driveway. I was on concrete the whole way... as such i found i could do very well with just three little piano casters which cost like $10 each. If you have to travel on uneven ground or across grass then you will need the scopebuggy or the JMI wheelybar with large wheel upgrade and in either case you are looking at $300+ excluding of course shipping.

here is what i used to use prior to just leaving my CPC1100 fully mounted and assembled outdoors:

Novalad, no problems with tracking or gotos. It almost feels like cheating. Smooth and accurate. Much to like in that department.

Hi Al,

I will have to wheel for about 20ft on concrete. Very creative the three little piano casters (one for each tripod leg, right?). You kept the CPC on the casters all the time, even when observing, I am guessing.

Thanks, Fernando

I think you've made a great choice. I don't think you'll see a lot of difference in the mount though, slightly dimmer power light, 4 degree slew speed instead of 3 and a clamped worm? I think these are all very minor upgrades noting I notice Celestron no longer say it has quiet slewing? The cpc was never quiet but I wonder if the new mounts slightly faster slew means its a little noisier?

Either way, when you look through it I bet you don't care. It will have superb views. Enjoy

Fernando-

For very smooth pavement they work great, even on a driveway with a few cracks and bumps they are fine if you are careful and slow in rolling it out. Yes I used to keep the CPC tripod feet on the little casters (they are quite small, but each is capable of 160# of weight!). Saved me $300 in not having to order JMI Wheeley bars and/or scopebuggy. Even better, I now have my CPC1100 outside for spring/summer observing somewhat permanently in the backyard covered with a Telegizmo cover, so I now use the little casters to wheel out my CGEM whenever I want a quick look as opposed to doing some video with the CPC.... Best $30 i spent in a while!

Boa sorte!
Al

Well? What did you get?

If you have not decided yet, go for the edge. It's not a fair trade off as it's 27% more expensive than the other one and the gains will probably not be noticeable on any given night.

But one night, at a dark site, the seeing will be perfect, the humidity non-existent along with dew. A very slight warm breeze will waft through carrying a pleasant tune. When you finally look through the eyepiece at your favorite globular cluster, your heart will stop for a moment as you catch your breath. Then, and only then, you will realize that this particular view was worth every penny, and the extra money spent was insignificant and a bargain at twice the price. You'll pack up the next morning with a satisfied smile and the only photographs you'll really ever need. The ones perfectly imprinted on your minds eye for you to pull up and revisit at a time of clouds.

Good luck with your decision.

Regards,
Stacy

Wow, that's a lovely way of thinking about it. Well the Edge here in the UK is 45% more compared with the regular. I am now waiting on the Bank Managers approval. If given the all clear I'll be ordering the Edge next week. If not then I'll have to think about settling for the regular.

Hopefully, it will go to plan and the Edge will be on its way soon?!

Just a quick follow up to this. I have after far too much deliberation finally ordered the cpc 1100 deluxe. Thanks to everyone who helped me make the decision, all helped. Of course if I don't like it I can blame you guys right and get a whip round for the refund?

Hey! You'll enjoy your new scope and I'll personally vouch to having no knowledge of any suggestions and/or recommendations regards said subject.

Hope the weather cooperates when it arrives and have fun!

I'd recommend some high end glass for the other end as well.

The ep I find myself using the most is a 17mm Nagler. A 13 T6 is also a joy. The Ethos are really nice but 2nd hand Naglers are a fantastic bargain. JMHO

Thanks, yes, I need to decide on a few eyepieces. I was thinking about trying to complete the celestron luminos line as I thought the 31mm would be useful. That and the supplied 23mm along with my baader zoom would keep me going whilst I looked to complete the range?

Any thoughts on the Luminos line of eyepieces?

Yes, I had a complete set of them. I probably overpaid for a few of them in the interest of completing the set, but got great deals on the ones included with the scopes (23mm I think?)

However, the ER can be tight and possibly a little under what is published. And I found the design to be a little uncomfortable to use (wide and flat on the top).

When I tried a couple of a friends Naglers and his 41 Panoptic at a star party once, I immediately sold the entire set to a gentleman in France and began acquiring used Naglers in a range of sizes and the 41 Panoptic. I cannot give you all the technical details of the difference in the view, but I will tell you the Naglers just looked amazing. When I discussed this with my friend (Spaced , of Goldendale Star Party fame) and my hesitation on the expense, he mater-of-factually explained "you only need a few, and you only need to buy them once".

At the time, the Ethos were just coming out and the used market was flooded with "like new" Naglers of all sizes from people who were upgrading to the Ethos. I took advantage of this and acquired 11, 13, 17, 20, 26, 31 Naglers a 2X Powermate and the 41 Panoptic. Of these I rarely use the 20, 26 or the Poewermate (not sure why, just seems to happen that way).

Anyway, the nice thing about it was it got me off the Eyepiece tread-wheel. I was always trading this for that and trying out one of these or those! I am extremely happy with my ep's and don't feel the need to shop anymore.

As far as this topic goes, I don't think you can do a whole lot better than gently used Naglers value-wise for your 11" SCT. As always, JMHO.

OK, I just checked. My Celestron EP's were actually the "Axiom LX", which was the predecessor to the Luminos. I think the Luminos might have slightly different specs. and be a bit more affordable. YMMV

Well I'd picked up a 23mm Axiom before ordering the cpc and am going to sell the axiom and keep the luminos. I always hear great things about the Naglers but don't see many come up for sale in the UK. The only reason I thought about the luminos was to build a set. I really wouldn't know where to start with the Naglers though?

I thought the 23 Axiom was the best of the bunch and might be a keeper over the Luminos.

If you were considering Naglers, I would start with a used 17mm Type 4. Great ER and probably my most used EP. If you like that, then you could build on it. Say an 11 or 13 Type 6 maybe. Check the various classified boards like here or Astromart. Many are willing to ship international. I have on many occasion.

A 17mm Type 4 just went on 5/1 for $230 on Astromart. That is what I would look for If I were you. Such a deal! New is $440 and I doubt you could tell the difference from new as most astronomers take very good care of their stuff and are honest about it's condition in my experience.

Personally, I believe that used Naglers represent one of the best values and possibly THE best value in eyepieces of any kind. I mean really, what can you get for $230 in a high quality 16-18 eyepiece?

Of course, these are just my opinions. Certainly there are many, many choices. Just head over to the EP forum where there are frequent knock-down, drag-out .... uh "conversations" about eyepieces lol. People can be quite passionate about their choices and reasonings concerning eyepieces.
