Finally--a stock 6" f/5 w/2" focuser--Omni XLT 150
      #5704610 - 02/28/13 12:47 AM Attachment (188 downloads)

I thought I would pass along the good news that the Omni XLT 150 (6" f/5 reflector) now comes standard with a 2" crayford focuser! I had read on CN in the past about the lack of this configuration on the market and I lamented over the cheap, plastic 1.25" focuser on my own Starblast 6 before I sold it off. Woodland Hills has been selling the OTA at an amazing price (first reported by Locoman) but I don't think anyone knew about the 2" crayford focuser being standard. Even Woodland Hills' own listing says 1.25" rack and pinion focuser and the main picture shows the old rack and pinion job, so I called them up to discuss. I spoke with Kevin Legore and he said that they need to update the listing as Celestron quietly started shipping these with the new focusers and they didn't even find out until they set one up in store for a customer. And if you want to upgrade it to a Moonlite or a 2 speed focuser, it would basically be a drop-in (with the proper curved base plate), no more cutting a bigger hole in the OTA.

I am pretty excited to have this decent aperture wide field grab'n'go setup. The Pan 35 yields a 3.0* TFOV and if that's too much exit pupil for you, the 22T4 gives you a 2.4* TFOV iwth a 4.4mm exit pupil.

I called them to see if they had them in stock and I was told they were. I ordered it but after five days and not receiving any notice of shipment I emailed them about it and received a reply that they didn't have them in stock after all so they put in an order for them to fill my order. A 2" crayford focuser would be a bonus but looking at your picture it doesn't look like a crayford style focuser. It looks like a 2" R&P focuser with nice focusing knobs! Am I wrong? Even if it is a 2" R&P focuser it would not be a problem for me because I know know how to make them work smoothly with no slop! Looking at the pictures at Woodland Hills it looks like a 2" focuser but I wasn't sure. And thanks for posting and your picture with it!

Locoman, the focuser is a true Crayford, same as the ones on other Synta scopes that came with one such as my Orion XT8i Intelliscope. Here the focuser is shown with the GSO 2x ED barlow minus the barlow as an extension tube with compression rings. Gotta love the versatility and usefulness of that barlow!

Compare that focuser with the old 1.25" rack and pinion focuser with big focus wheels, see the picture below taken from CN'er fuadramsey's archived thread.

Locoman,

I am sorry you were not informed sooner about them being out of stock at that time. These little guys sell fast but are a a regular stock item. A few more arrived yesterday, I believe 4 of them if Im not mistaken.

Very Cool. I really like this size scope-- Perfect sweet spot for grab and go, relatively little coma, and works well for nearly all targets, as long as the figure is good. Mine is an old Vixen with a 1.25" sled focuser and a atm primary. I really wish it had a 2" focuser.

What size is the secondary? The description says something about a 1.25" STAR DIAGONAL. Normally the term "star diagonal" would refer to a diagonal mirror in a refractor or cat, so I'm not sure...

I think it's an error. The secondary is about 2" minor axis.

BTW, it's a little bit of a mystery to me that scopes like this seems to have been unavalable in the states until now. I thought they were common. They've been readily available here in Europe for some years now.

Thomas, I guess we were due! The last 6" f/5 with a 2" focuser in the US I think was a SkyWatcher that they were blowing out a few years ago. IIRC, the focuser may not have been a crayford and the figures on the mirrors were not so great, so not quite the quality of the Omni.

I do like those SW reflectors with the two-speed focusers, that you linked to, they look pretty nice.

We Europeans used to look with envy at the US and all the nice gear that was available and anything new seemed to be introduced there first and would only later eventually trickle down to us in Europe. Now it seems to be the other way round and we get to see much of the fun stuff first. The selection available here is certainly impressive.

No problem, I appreciate your posting about them and I wasn't trying to degrade your company in any way about my order with you. I understand these things just happen and I'm not concerned. You have great products with competitive prices. I have purchased other items from you before with no problems and will probably will again! Thank you!

At the Woodland Hills page, the ad copy states:

"A 750mm focal length and focal ratio of f/5 presents an image ideal for both visual and astrophotography use . This baby also comes with a 1.25" star diagonal, 1.25" rack and pinion focuser, and high quality Celestron 25 mm Plossl eyepiece. The finderscope is a straight-thru 6 X 30mm achromat."

On the specification table, it says the focuser is "helical"

?!?

What a great price, hard to beat $60 for a real telescope. That is 50 times less expensive than a 130mm refractor, is it 50 times less useful? lol

Wow! One nice thing about a scope this size: you can even just put it in your lap and scan the skies with a wide-field eyepiece. A friend has one of the ES MakNewts mounted as a ‘finder’ on his 22-inch Dob.

If I didn’t already have my ATM 6” F/5 with a moonlight focuser, I’d order one of these. My scope was built around an old commercial mirror set that was not very good. OWL re-figured it for me for a reasonable price with a very short turn-around. However, I bet I have a lot more than $190 invested.

I put it up to my tv genesis that it's next. looking at saturn it was only a little softer. I was realy suprised at the magification it took.

so $60 compared to tv genesis could go for $950 but when original how much was it?

Not a correct image but an upside-down image, not sure if it is mirror image but I never considered using it anyways.

The 6x30 finder looks like the same that is supplied on many Celestron, Orion and SkyWatcher telescopes. It produces an inverted image, same orientation as in a refractor without the diagonal or in a Newt. The image is just turned 180 degrees.

Well, I ordered one of these 6" OTA's this past Saturday night. I've been looking for a 6" f/5 Newt with a 2" focuser for a long time. I want to maximize the aperture and ease of portability and minimize the weight and cool-down time for a grab-n-go scope. I define grab-n-go as one trip out the door, telescope on mount. Anything else is not really grab-n-go.

I also like the image orientation in a Newt: inverted. Ideally, I'd want the natural orientation, but that is difficult to accomplish optimally except for binoculars. I don't like a reversed image as in a refractor+diagonal, Mak or SCT.

The fact that the Woodland Hills vendor verified that these XLT 150's are shipping with a 2" Crayford closed the deal for me.

Looks like I might be selling my 130mm f/5 Newt soon.

Maybe I'll do a three-way shootout among my 6" f/5 Newt, 6" f/12 Mak and 6" f/15 SCT. It's difficult to justify keeping all three now.

Get this from the ad patter for the Omni XLT 150:

Quote:

Using aspheric shaping technology in conjunction with hand-figuring the optics, the Omni XLT presents an image with virtually no spherical abberation.




A fancy-shmancy way of saying the primary is parabolic.

Several Danish imagers use 6" f/5 dobs and they do very well indeed. You need a coma corrector, of course, like for any other f/5 newtonian.

This image, for example: http://www.astronomibladet.dk/images/stories/aktivastronomi/m81-m82.ed1.jpg

is taken with a Sky-Watcher Explorer 150 on an EQ-3 mount with a Canon EOS500D, by danish amateur Henrik Rosenørn. The Explorer 150 is virtually identical to the Celestron Omni XLT 150.

Joe, I enjoyed reading your excellent review of the Omni XLT 150 (old focuser version) while I waited for mine to arrive in the mail. The comparison versus the Astro-Physics 155 f/9 EDT was enlightening. Also, you're right about that faux-Pentax freebie EP that comes with the scope--it's not too shabby!

Orion discontinued their 6in imaging newt.
It had 2in crayford with fine focuser and built-in extension tube.

Try using WO binoviewers with the newt.
Nice comet scanner.

Interesting! This looks like it would be a great grab and go scope. I don't have any mount for it.

What would be a good but simple mount for this scope? Something like the mount in the op photo? What is that one?

Mr. Bergeron,

The main reason I bought the Omni XLT 150 last May (2012) as my first scope was because of your review. It was excellent! As a matter of fact I still refer to it.

I did update the mount to a GPD2 in part in anticipation of buying a larger OTA.

My only real complaint of the scope is the slop in the focuser, which has become more apparent with the GPD2.

So, now I formally thank you for your informative and well written review!

It cannot go 90 degrees, maybe 80 degrees if my memory serves me well. It is like a dob on a tripod and with degree circles. Very smooth, light, transportable and easy to use.

I did this to the focuser on my C6-N and it is very smooth with no slop. I added two strips of teflon to the upper draw tube directly opposite of the ones on the bottom and the focuser is now light years from what it was!

I just did quick scan of the link you included. Will certainly investigate this option further. Could be just what the doctor ordered .

Thanks again.

The mount is the Astro-Tech Voyager as seen with the extension pier accessory. With this configuration, I can see up to the zenith without any issues. With the tripod legs fully extended, the eyepiece height is quite high, which I like since I am 6'2" and can standing up without having to bend at all. You do have to be careful that you don't accidently bump the setup, especially at certain angles as it can tip over due to the uneven weight distribution. Overall though, great mount and a nice setup so far. The problem is that the mount (and extension) are tough to get new. Astronomics had them on backorder most of last year, now both items are on a wait list. Best bet is the used market.

I have the AT Voyager mount and extension. The extension is useful - maybe necessary - for some longish telescopes that might hit the mount when pointing toward zenith. But the extension adds appreciably to the weight and cumbersomeness of the Voyager mount. That's not good for optimal grab-n-go. I'd rather leave the extension off if I can.

One way to get around needing the extension, is to mount the OTA higher up on the dovetail saddle. Then the bottom end of the OTA will clear the mount when the scope is pointed toward zenith. I was able to do this for my 5" f/5 Newt OTA, but I had to add some weight toward the bottom end of the OTA as a counterbalance. Hopefully I'll be able to do the same for my 6" f/5 OTA.

By the way, I like to sit when I'm observing. I was able to do that with my 5" f/5 scope.

Got it. Thanks.

Tube interference is something I find difficult to resolve with 6" scopes on grab and go type alt-az heads and tripods.

I have a Unistar on a heavy duty surveyor tripod that works perfectly with my 6" f5, but not with my 6" f6. On the f6, the tube hits the mount near zenith, and the ep is just out of standing height (tall tripod, even compressed, for refractors). Funny how much difference f5 vs. f6 can make...

I have the Skywatcher 130/650 that I picked up at NEAF for $50 a couple of years back. I recently upgraded to a 2-speed crayford focuser. I use it on a Vixen Portamount and an LXD 55. Great little scope.

I have enjoyed my C6-N very much to. A 6" f/5 newt on a simple Alt Az mount is simply a joy to use! So I couldn't let the XLT 150 go especially since it has a 2" crayford focuser.

you can use any low profile focuser and make an adapter plate cause the SW has a 2.5in focuser which has a large foot print.

My Omni 150 edition has the 1.25" focuser. I never considered upgrading to a two inch. The thought of cutting metal is not appealing. Future plans call for an 8 inch OTA from Orion and I will install a moonlite on it. But I will never part with the Omni 150; it is so easy to set-up. Plus, it is my first scope. I remember the first surfboard (new) I bought. After 3 years I sold it to get another and it was a terrible mistake, both from a technical and emotional aspect. None of my other boards, except for one my surfing buddy gave me, did I ever have such an emotional connection with.

Try using WO binoviewers with the newt.
Nice comet scanner.




I don't think I've ever binoviewed with my dob--would it be easier with this scope? For someone with not just 1 but 2 binoviewers I am pretty clueless about using them in a newt.

I am able to easily bring to focus WO binoviewers on Vixen 130mm f/5 and Orion 150mm f/5.
Note: these short newts needed an extension to focus "cyclops" style.

I'm definitely going to try that out. Might need to add a counterweight on the OTA with that setup, though.

Usually, there is not enough inside focus to accommodate a binoviewer on Newts. That is how my 8" f/6 and 10" f/4.8 Dobs are. For them to come to focus with a binoviewer, I need to insert a Barlow or OCS.

So are you saying the 5" f/5 and 6" f/5 are able to come to focus with the binoviewer without a Barlow or OCS, and that they need an extension to come to focus without the binoviewer? I guess that's one way to keep the OTA short, though it means they should put in a larger secondary.

I'll check my little Newts out with my Burgess binoviewer and see for myself.

I have the same 'scope, but replaced the plastic R&P with a Taiwanese Crayford. Stripped the anodizing for a Wyorock look. Bought the OTA for $50 (shipped), the Crayford for $50 (shipped) and added a Vixen shoe for the finder. It is a whole lot lighter than my 6" f/5, but I can tell I am not looking through the 6".

Yup, I called mine in. Although I have not had issues ordering on-line before. Had to make sure I was getting one with the 2" focuser, did not want to end up with an old stock one with the 1 1/4". That would have made me upset, lol.

I called and asked if it was in stock before I ordered it and I was told it was in stock so I ordered it online but the person I spoke to was mistaken. I understand mistakes can happen so I am "Patiently waiting". I'm glad I ordered it when I did because I got in on the free shipping! It will get to me someday!

Locoman,

What exactly do you mean by "free shipping?" You bought the 6" OTA by itself with no shipping charge?

Woodland Hills has free shipping for orders over $200. I just added enough small items that I needed anyway to top $200 in order to avoid shipping charges.

Hello Mike,

They were selling the scope for $189 with free shipping as a special for a while. That special is now over.

The ad on there web site said "Free Shipping" when I ordered it! I don't think it was a special because it was free free shipping for a long time and the C6-N that they sell came with free shipping to for a long time but the free shipping went away the same time as did the 150 XLT.

Has anyone else received their scope yet? I ordered mine 15 days ago and am still waiting for an email with tracking number. I received a couple accessories that I ordered along with the scope, but no scope so far.

I may cancel if I don't receive a "Your Order Has Shipped" email soon. The more an order is delayed, the longer I have to reconsider the purchase, and the higher the probability that I'll cancel it.

I already have a 5" f/5 Newt with a 2" focuser. But the 6" f/5 will give me greater light grasp, a not much smaller TFOV and a Crayford focuser. The focuser looks low, so it should give me more flexibility in the eyepieces and accessories that will be able to come to focus. I will probably sell the 5" f/5 when/if I receive the 6".

Hello Mike,

Hope you are well.

Give them a call it is a toll free number. They told me that they regularly get stock of these telescopes and that they are selling out rapidly. They will know when the next order is in, and you can make sure that your order did not get lost!

So far this telescope has got to be the bargain to beat at the moment. Where else can you get 6" of aperture for the price of a 2" diagonal? I mean if I had to build this telescope it would cost me way more in parts than buying it as a whole. Worth it to call them.

Later,

Tony

Yeah, I just gave them a call right before I posted my last message to this thread. Someone is supposed to give me a call back. Hate that.

The idea that an order can get lost infuriates me even more. It has happened to me before, for example, when I ordered a new Moon Atlas not long ago from a different vendor ('nuff said). I believe someone in Eastern Europe got theirs before I got mine ... because they had lost the order - actually, they never even opened my email! Even the most intelligent people can be ... never mind.

But in this case, they got the order, got my money, and have sent me a couple emails ... just not an email saying the scope has shipped.

So how could they have possibly "lost" my order?

Well, it's been 30 days since I ordered my 6" OTA. Still no email saying "Your Order has Shipped." Still no scope. Has anyone else received theirs?

Anyone else thinking about cancelling their order? I think mine was already charged to my card. Not good.

Mike, maybe a call to High Point is in order. As for do you need it? Well, aperture increases are always welcome and I'm sure you could raise half the funds from the sale of the 5" reflector. This super cold "Spring" makes the waiting a bit easier.

I didn't order it from High Point. What does High Point have to do with it? I ordered the telescope from Woodland Hills.

I already called them on 3/18/13, about two weeks ago. Read about it in my post farther back in the thread.

I just looked at there web site and your right, I can't believe the price went up $80.00. They still list it with a helical focuser and a diagonal. I ordered mine on Feb 22nd and was told when I ordered it that it was in stock but I am still waiting. Not good!

the price changed this morning or last night,
http://www.ebay.com/itm/Celestron-6-Omni-Reflecting-Telescope-Short-Compact-2...

these from other dealer, I called them, looks like no factory warranty, just "store warranty", i guess $190 OTA should be customer no reason returning. but "like new" condition. if $190 with "free shipping", that should be with defect. they just want to clear out. Celestron maybe stop provide OTA to WH. That is why "Call for Availability".

If price around $300 I prefer to choose Orion 8" OTA.

The Orion 203 OTA is 11 1/2 inches longer and 4 1/2 lbs heavier than the Omni 150 which would require a beefier mount than what I have. WH's does have the C6-N (which I own) for $199.00. Just add something cheap to make it over $200.00 and you would get free shipping. The focuser is it's only drawback but I have reworked mine and got excellent results.

My XLT 150 arrived yesterday via UPS. They always deliver at about 11:30AM when no one is home. Woodland Hills set up the shipping for signature confirmation, although I had sent them two emails requesting no signature. I had to go on the UPS website and waive the requirement for signature, otherwise I'd have to take off a day of work. Not a good thing, but not out of the ordinary for vendors.

So far the scope looks fine. No obvious dents or other problems. Of course, the Curse is in full force. There will be rain and clouds through the weekend. But I intend to star test the scope on the first clear evening. I can just set it up on the porch and aim at Polaris.

In the meantime I can mount it on my AT Voyager alt-az. The OTA is pretty long, longer than I had expected for an f/5. I might have to attach the extension to the top of the Voyager so the bottom of the OTA won't strike the mount or tripod legs.

I have a CG4, but I won't bother putting the scope on that mount. I really don't like GEMs, especially for a Newt. The XLT 150 will max out at about 300x, 50x per inch. I have no problem nudging a Newt at that power. The Voyager has slo-mo controls, so all the better.

Actually, i think it is a little shorter than it normally would be (hence that included extension adaptor). I have had mine on the AT Voyager a could times, just to check it out as to alignment, contrast etc. I was surprised how well it balances on that mount. Have not tried to point it straight up though. Fair amount of shake at the eyepiece though.
Intend to use it on my still to be delivered DSV-3 mount.

It was longer than I expected, but then I've never had a 6" f/5 Newt. I do have a 5" f/5, which might be for sale soon depending on how well this 6" turns out.

Did you have the extension on the Voyager? I'd rather not have that on the mount, because it adds to the weight and cumbersomeness of the setup. But an extension might be necessary so the OTA won't strike the mount or legs. I don't like having to keep turning the tripod to clear the OTA.

If I use heavy 2" eyepieces - such as my ES 82 30mm - on the XLT 150, I'll have to either move the OTA way down in the rings or add a counterweight to the bottom end. Actually, I've done both for my 5" f/5. I have a small sports-pack filled with lead shot strapped to the lower end of the OTA.

What is a DSV-3? I'm full up with mounts now, but I'm curious.

Nope, do not have an extension for that one. I am not getting the DSV-3 just for the scope we are discussing, but it should nicely over-mounted on it:

Here you go:

DSV-3 ALTITUDE-AZIMUTH MOUNT

$740 for the mount head. Too much for me at this time. I'll make do with the Voyager for now.

It might make sense if the observer had several scopes they could mount on the DSV-3. Yes, I have several scopes that would fit, but still ... maybe sometime.

I tested my XLT 150 last night on my porch. I mounted the scope on my Voyager alt-az. First I let it acclimate for about an hour. The test star was Polaris. Seeing was about 3/5. According to CSC, the seeing was poor, 2/5, but I don't think it was that bad. In fact, I know it wasn't.

I put in my Brandon 6mm for 125x, 20.8x per inch, 1.2mm exit pupil. At about 10 wavelengths, the diffraction pattern looked virtually identical on both sides of focus. I could see no appreciable difference. At about 5 wavelengths, inside focus showed a darker separation between the outermost ring and the next ring in, than appeared outside focus. But this difference wasn't always as prominent as I switched quickly between the 5 wavelength in and out of focus settings. I also tested with my XO 5.1 for 147x, 24.5x per inch, and 1mm exit pupil. The results were the same.

I'd like to test the scope again during better seeing.

Later I took the XLT 150 out for its first light. It was easy to carry the mounted scope down the five steps of my porch and around to the side of my building. I observed the Moon and Saturn. The Moon was gibbous, 10 days old and at 75% illumination. I used my Brandon 6, XO 5.1, and TV 3-6 Nagler Zoom. In all these eyepieces, the Moon showed good contrast and good surface detail toward the terminator. The three major Rimae Hippalus were easy, with suggestions of a fourth. I also saw the network of Rimae Ramsden. Volcanic dome Kies Pi was visible. I could use the Nagler Zoom down to 3mm for 250x, 42x per inch, and still see a good image. The only problem was the 0.6mm exit pupil, which made my eye floaters very obvious over the bright lunar surface.

I could not see any definite craterlets in Plato, which surprised me. Maybe Plato was too far away from the terminator for adequate contrast or the seeing needed to be better? I'll have to try that again at another time.

I also looked at Saturn with the XO 5.1 and Nagler Zoom. The image began to become less sharp than I like below about 4mm (187x, 31x per inch), probably because of the average seeing. I could see Cassini's Division around nearly the entire visible ring. A wide, dusky SEB was easy, and the SPR was nearly as easy to see.

Due to competition from the bright gibbous Moon, I did not bother to look at any DSO. I planned to use this 6" f/5 Newt mostly for wide field DSO at a dark site when I go there with my family, and don't feel like stuffing the vehicle with my 10" Dob. But judging from the results with the Moon and Saturn, it should do well with deep sky, also.

I really should fully flock the OTA and the focuser. A fan for the primary mirror would be nice but not an absolute necessity, especially for DSO.

As Moynihan mentioned, the OTA is shorter than it optimally should be. With the 1.25" visual back in the focuser, I needed to edge some eyepieces a little bit out of the focuser in order to come to focus. These were the Brandon 8mm and 6mm, and the TV 3-6mm Nagler Zoom.

The OTA should have been made longer. This would have allowed a smaller diagonal and a lower profile focuser. I intend to take measurements of the scope, plug them into NewtWin, and generate the specs, especially the CO %.

I first-lighted mine back on 3/3 from my neighborhood (white zone) in poor transparency, poor seeing conditions. There was still a lot of snow on the ground at the time and it reflected a lot of light back up into the sky, worsening the already poor conditions. I observed Jupiter, NGC 2362, M67, M44, Saturn and attempted the Leo Triplet (0/3). Still, images were crisp and enjoyable, though I did not do any critical testing of the scope and was just glad I had a chance to get it out.

Like you said Mike, this will do best as a widefield specialty scope under dark skies. I top out at a ~3* TFOV when coupled with my Pan 35; I cannot wait to try that at a dark site, scanning the Milky Way!

that would be good for doing prime focal photography or binoviewing.

I have absolutely no interest in photography ... but I do like binoviewing. I'll have to check that out! It would be great if I could binoview this 6" Newt without having to use a Barlow or OCA.

Has anyone else binoviewed the XLT 150?

Well, I took the XLT 150 out this evening for some Moon viewing. I also brought along my binoviewer kit for experimentation.

No real surprise here: The binoviewer could not come to focus in the XLT 150. No shocker, since I've never owned a Newt that could focus a binoviewer without a Barlow or OCA. Just not gonna happin'. Maybe folks with a truss scope can chop down some struts to get a binoviewer to focus. Forgetabout. I don't need a native focus binoviewer that badly.

In any case, I slipped on a 1.9x OCA and binoviewed the Moon for about an hour. I used the following pairs: TV Plossl 26, Meade 5k SWA 24, TV Plossl 20, Brandon 16, Brandon 8, TV Plossl 11 and TV Plossl 7.4. These pairs gave me powers from 55x to 193x. The higher magnifications were a little much for the seeing, which was only about 2/5.

I ended up removing the binoviewer and just using the TV Plossl 7.4 at 101x. Once again I was pleasantly surprised by the TV Plossls for lunar, something which goes against the usual consensus. I actually liked the view through the TV Plossls better than the Brandons. For whatever reason, at least sometimes I prefer a warm view for lunar rather than a pure white tone.

What I wrote above is my first light report! It's not much, I know. I really do need to get in more time with this scope.

Glad to hear that it can be BV'ed with, even though an OCA is required. The powers are pretty low and fields pretty wide, still, I would imagine, even with a 1.9x OCA.

I received my 150 xlt yesterday with no damage at all. It sure is a good looking scope and the two inch crayford is a big bonus. First light may be a while though!

Last night I made another attempt to come to focus with my binoviewer in the XLT 150. I took the stock 1.25" adapter out of the focuser and inserted the low profile adapter from my Paracorr. I put in the binoviewer and tried to focus on the Moon from a window in my house. I used the same eyepieces as when I binoviewed the Moon a few nights ago.

None of them would come to focus with the binoviewer in native mode. Not even close. Maybe if the 2" focuser were replaced with a low-profile it could be done, but I doubt even that would work. Anyway, I don't think it would be cost-effective. I'm not doing it. As I said, I've never had a Newt that would come to focus with a binoviewer without using a Barlow or OCA.

I also looked at Saturn with the XO 5.1 and Nagler Zoom. The image began to become less sharp than I like below about 4mm (187x, 31x per inch), probably because of the average seeing. I could see Cassini's Division around nearly the entire visible ring. A wide, dusky SEB was easy, and the SPR was nearly as easy to see.




This needs to be corrected. It was the NEB and NPR, not SEB and SPR. My excuse is that I had recently first lighted a 6" SCT, which does not flip the image - a source of confusion between the two scopes. I try to catch these mistakes before the editing time-limit elapses for a post.

Last night I was playing around with my 8"f6 tube dob using the binos with no compensator.

I pointed the scope at zenith and with the primary sitting on a "pedestal"[a paint can] I slid my tube down till I could reach focus.

The primary wound up 4" in from standard position. When I put the numbers in newt for the web, I'll have to change the secondary from 1.5" to a 2.14" to get 100% light.

So if you want to use the binos with no compensator you'll have to use a different cell mounting plate that allows you to move the primary a lot closer to the secondary [4"]. I'm sure your stock secondary is big enough, they tend to oversize them...

I have a Z8 f/6 which is probably similar to the Dob you're describing. The stock diagonal is somewhat oversized. I actually canabalized a smaller diagonal from a 5" f/5 Newt to replace the one in the Z8, to achieve a smaller CO%.

For myself, I'm not too gung ho about moding any of my Newts so they would be able to binoview without an OC or Barlow. My old model Burgess Binoviewer has a relatively narrow CA in any case, so there wouldn't be much point to it. I use my binoviewer almost exclusively for planet/lunar. I'm not really too interested in binoviewing for low-power wide-field.

I suppose, though, that moding the 6" f/5 for richfield binoviews at a dark site wouldn't be a bad idea. I guess I could raise the mirror cell up somehow. I have an old mirror cell from an ancient 6" f/8 in the attic. For richfield, it might be a good idea to take the diagonal that was in my Z8 and put that in the 6" f/5.

But then I should replace my binoviewer with one that has a wider CA to accommodate the wider field stops in low power eyepieces. Then it starts to cost some money. Otherwise it would be a waste of time, because there would be vignetting in the binoviewer with loss of light and constriction of the effective field of view.

I had mine in my 127f5.5 fractor this last weekend at a dark site and some of the views were awesome. I took off the corrector and removed the diagonal, and while looking around aruiga I couldn't keep my mouth shut. and everything was crisp. it was low to the horizon so I could set it up as a straight thru view. later while it wasn't even totally dark yet I had m81&82 in the same view with the diagonal and 1.6 comp. 82 was very distinct.

I spent more time with my 127 and bino's than my truss 8"f6 that has a good figure on it.

I got a chance to second-light my Omni XLT 150 last weekend at a club observing night... There was a waxing Moon to contend with but splitting doubles in Lyra and views of Saturn were pretty good. Seeing was only average, though and the CD was elusive in all scopes out there that night. Views of M13 were decent as well, I thought a bit faint at 150x. I realized later on that my XW 5 was NOT in the focuser (150x) but instead the XW 7 (107x), so that explains that.

CN'er JimMo let me try his ES100 25mm in the scope--3.3* TFOV, 30x, wow what an immersive view! I didn't even have to rebalance the scope. One thing I must add though, the XLT 150 was very shakey for some reason on the AT Voyager mount. So shakey that when other observers walked around near the scope on the pavement, the scope shaked A LOT and this was with the extension pier on the Voyager mount. I'll have to make it a bit more stable...

Anyone sells the new version OTA-only with a 2" focuser? Telescopes.net advertises the model with the 1.25" only, according to the site.

It's said that since Lincoln was President. It's been pointed out repeatedly -- the specs say its a helical focuser -- the ninnies won't update it. LAZY. However, if you call them, they will swear on a stack of Bhagvad Gitas that it ships with a 2" single speed Crayford (à la Orion dobs). Don't let their poorly maintained website fool you.

I finally took out a telescope last Friday after three months of recuperating from back and hip injuries. Not my 10" Dob, but this XLT 150 on a Voyager II alt-az mount. I didn't want to take a chance on a relapse.

A star test on Polaris showed that this 6" f/5 Dob has a somewhat different diffraction pattern when comparing infocus and outfocus at 5 waves, not so much at 10. Maybe 1/5 wave lower order spherical aberration when comparing my memory of the diffraction pattern to examples I've seen online. Unfortunately I didn't have Suiter's Star Testing with me. But so far my C6 SCT seems to have a better star test than the XLT 150, with no difference seen at 5 waves with the C6.

I need to do a more thorough star test of the XLT 150 on my porch at home, viewing Polaris, with my copy of Star Testing at my side. I don't like to spend much time testing equipment when I'm at a dark site.

(I've given a more detailed account of my observing session in another thread.)

Even if it's a 1/5-wave mirror, that 6" f/5 reflector is going to be waaaaaay sharper on planets and globs than a 6" f/5 achro. I think it's really cool there's a 6" f/5 reflector out there with a 2"-focuser that sells for as little as a it does. I had a 6" f/5 Celestron Omni achromat that was great for a widefield viewing, but a 6" f/5 achro is a "widefield uber alles" scope. Get the power above 100X, and things started getting ugly on planets.

At the time, I couldn't get a widefield instrument like this with a 2" focuser unless it was a fast achromat. It's refreshing to see a far more versatile instrument with the same aperture and focal length being marketed out there.

Clear Skies,
Phil
