Celestron C90's

I have seen several C90's up for sale lately. I do not know much about these scopes, but they look like fun to play with in front of a DSLR or other camera. Do they support 1.25" standards? I think some may be the .96" stuff. Anyone got any input on this line?

Thanks!

Keith,
The C-90's come in several flavors. There was the standard orange tube spotter with the photo tripod mount. This style also came in an astro version with a single arm slimmed down version of the C8/C5 fork. There were also rubberized versions and black body versions.
I have one of the earlier orange tubes. In the early 80's, I kept the unit in my van attached to an OM-1 with Focus Screen 8 or 9. Pulled it out whenever I saw something unusual. Loved it. Front barrel focus just like a regular camera lens. With 800/1600 asa, I was often shooting at 1/500 or 1/1000 sec. Did everything from still life macro to radio controlled planes in flight. (They filled the frame, looked like real planes shot with a regular camera up close.)
By default, the C-90 is designed to take .965 eyepieces and a special T-adapter, but you can get a LAR (Large Accessory Ring) and use standard SCT accessories. That is what I had, a LAR and standard SCT T Adapter. Fit my hand well and was well balanced. If I had a good DSLR today, I would use it with my C-90. jsut can't afford one.
I even mount mine piggyback on my C-8's to give lower power views compared to the C-8 when doing public sessions. (Front barrel focus when mounted piggyback is a pain though.)
