Another Great Orange 8 SE OTA!
      #5689378 - 02/19/13 05:52 PM Attachment (93 downloads)

It arrived safe and sound yesterday evening bringing with it plenty of rain/clouds of course! There goes the week+.

I got this new ota from High Point Scientific to replace a black tube SP C-8 (special coatings only) I've had since 1985. I still have the Super Polaris mt. and am getting a ADM vixen saddle for it to use with other ota's and also to use it with this new C-8 some of the time. For goto/ tracking I can use it on my CG-5 mt. or CGEM which is why I didn't buy the SE mt.

Everything looks/functions in perfect order with this ota! I notice the Fastar compatible logo on the front of the secondary -- that's nice, but I don't plan to do AP with this ota -- and the dust-cap fastening is improved since the old C-8 with a bayonet-style twist-lock, plus tabs. The old C-8 dust cap would easily fall off (once it actually blew off when the wind picked up during pack-up to leave a dark mtn. site) and the tabs on it were rather fragile.

It'll be a while before this C-8 gets to see first light, the weather here has been so rainy. Although the Voyager isn't to be the primary mt. for this C-8 I put it on the Voyager alt/az mt. just to get it set up somewhere for the time being. It weighs less than my AT90 EDT refractor! It's about the same length as the AT90 and the Voyager carries it fine for visual. With the arm attached straight up there's clearance for near zenith views and the pier extension puts the eyepiece at a good height for me to stand or sit while viewing.

I already have a Celestron f/6.3 reducer/corrector and plenty of other gear for a standard C-8 so didn't feel I needed the Edge HD.

Here's a few pics ...

Don't know why they ever started making them any color but orange. It's a beautiful scope. Congrats!

Nice looking OTA. I was very impressed with the capabilities of the 8SE OTA. I just recently sold my 8SE after getting a NS11GPS with the carbon fiber OTA.

Here's hoping you get it under some dark skies soon.

Thanks Joe! I agree, and I've always loved the original old orange tubes. I think the deep orange metallic finish of the new ota is very attractive.


Thanks Richard, and congratulations on the NS11GPS also -- very nice!

Congrats, and beautiful looking scope. If you haven't already sold your original Black tube C8, it would really be interesting to hear of a 1 to 1 comparison between both scopes, to check the difference in contrast, image brightness, and darker background due to the better coatings, and differing optical corrector glass.

Maya i recently bought one of those orange C8s and the optics have been fantastic, better images than my 6.5" and the 4" ED.

Hello,

Congratulations to your new scope!!
Beutiful looking SCT; sure all C:s SCT:s ought to be orange! Would be kind if you send a 1:a light report.

Clear Skies,
Magnus

Thanks for the great replies everyone!

Stan -- terrific looking set-up! (love the avatar as well - I'm a Scrat fan too)


Bob -- yes, that would be an interesting comparison of the new C-8 with my old 1985 one with just the plain special coatings. That old C-8 was my first decent scope and there's a lot of good observing memories associated with it.

Julio -- Congratulations on your C-8 too! Have fun with it!

zAmbonii -- Wow, that's a cool Jupiter animation! Lots of great detail -- even some on the moons. Thanks for posting your AP work, it's inspiring!

magnus -- thanks so much too! When I finally get some good weather I'll really enjoy getting this new cat out for a spin, do a first light report, and drag out the old cat too to strut its stuff.

I had one these Orange 8SEs. It was one of the finest optics I ever had. Star images were pinpoint. I sold it for various reasons but recovered from my error by recently buying an Edge 8 which is thankfully just as good. A really sharp and well corrected 8" SCT is an awesome and versatile machine ...John

Congratulations on your Edge 8, John! Celestron has really made some great design strides/improvements with their SCTs in recent years, they continue to be extremely versatile and just plain fun to use too!

I had a carbon fiber XLT C8 but it had horrible image shift, so I kinda used that excuse to sell it to a friend who uses an external focuers anyways on it, so I could get me an Edge 8 HD. There was absolutely nothing wrong with the sharpness at the edge field of view, even with a 41 pan with my C8, so I still was wondering what they hype is on the Edge scopes. In the interim, I started using a C6 orange tube and found the focuser and optics to be 100 percent rock solid and accurate, and love the new orange paint jobs.
Having done a side by side finally with that former CF XLT and a new Edge, I still haven't been able to see a difference in the two scopes visually, on large open clusters regarding sharpness, even when using a 21 Ethos in both scopes.
Now I have my eye on an Orange tube C8 because I like the classic Orange slightly better than the white, but both i like much more than the gray tube C8's.

The orange to me is a coppery-orange tone. Kinda reminiscent of an orangey topped Duracell battery. The highlights and flecks in the paint in sunlight is stunning. I don't think they've ever looked as they do today. I love my C6 - inside AND out.

Your picture is a great shot.

In particular, it shows a feature that was the center of a big discussion on the CN Solar System observing forum.

I had made a post where I had described Io as showing a distinct pearl-like appearance due to the northern and sothern polar shading.

Several other observers were keen to repeat my observations, but when using smaller scopes, they said that Io looked distinctly oval.

In the C14 of course it was round but the C14 has far more contrast transfer. The observer using an 8" scope reported the pearl-like effect, but the observer using the 6" scope only reported that Io looked oval rather than appearing as a round disk.

Your picture shows this quite well. The contrast of the northern and souther poles is just enough that in the picture you can see that they are present, but the brighter equitorial region is shown as being brighter and gives an oval-ish appearance if you don't look closely for the curves of the limbs at the poles.

A great picture though and I am sure that you do have better ones because I know I have seen a few taken with C8s over the last 5 or 6 years.

It is so astonishing that ground based observers using modest sized telescopes can capture picutures of Jupiter that were beyond the capabilities of very large professional scope 50 years ago.

Software and CCD cameras. I love living in the future.

I remember a month or so ago about a discussion on the shading on Io in the SS imaging forum. At the time I never really knew about it, and thought that any ovalness in Io was due to orbital movement during the time of capture.

When imaging it is sometimes tough to capture some of the details in the moons because the exposure is set on Jupiter itself and sometimes after processing Io looks blown out and the other moons are a little too dark.

I upgraded my imaging at the end of the December, but weather around here has been so crummy that seeing was never better than 3/5 during that time. I do want to note that in the image above, the scope was out of collimation (as my post in the other thread) and I was seeing some of the same arcing around Io, and you can barely see it there. Would really like to get some good seeing and the scope in good collimation to really see what the new camera can do before Jupiter leaves us for a while.

I am also amazed what I can get out of imaging with this scope. It was only a couple of years ago that the only good images of the planets on the SS imaging forum were coming from scopes 9" and larger with mono CCD cameras that cost $400 or more.

The camera I took the above shot with is actually a USB 2.0 CMOS color camera with good enough sensitivity that I can capture at 70 fps or more. They just released a driver that can capture 640x480 at 113fps! That is a lot better than the webcam I was using that could only capture at 20fps.

I have an 8se and 6se and both have fantastic optics. Celestron has really improved the quality of their SCTs.

Awesome Jupiter photo also.

Great results! Things have really come far since I last dabbled with planetary ap with a regular 35mm film camera Canon F-1 (built like a tank and weighed about as much)! Seeing your results makes me reconsider trying planetary ap again with the C-8!

Still waiting for a clear night sky...but did get the ADM Vixen saddle and installed it on my old 1985 Super Polaris mt.

Worked out great, fits perfectly, gives the old mount more ota options! The combination of the wooden legs coloration and the new C8 ota actually looks pretty nice so I thought I'd add another pic. It's ready to go!

Thanks! That mount still works like it was new, though it's got plenty of mileage on it from carrying the old black tube C-8 on many a observing session around the country. I love how the new C-8 SE fits it just as well.

I've always heard good things about the Super Polaris mounts, I never owned though. However I did own a regular Polaris mount it was a gem to use.

Well... yeah!

Here's that old gem way back in '86 carrying the original C-8 ota and a 5.5" f/3.6 Schmidt-newt Comet Catcher (I still have). It weighed about 7 lbs. so that was the max I ever loaded it with. The Comet Catcher gave a nice wide true fov of 2.63 degrees to alternate with the C-8's. These days there's much better options and wider fov possible with some small refractors.
