Quote:Hi Sam, Take a look at the 2" visual back adapter for the 9.25" SCT from Astro Physics: Astro Physics 2" Visual Back Look under "Accessories"/"Focusers, Adapters, Extensions and Covers". It has 3 thumbscrews and a brass locking ring. I have one on my 12" SCT and at $40 dollars it's a steal!For a quality 2" diagonal ... I'm sending you a PM with information on a soon-to-released, comprehensive test report on over a dozen 2" star diagonals. And the winner is ..... ?????Jim

Quote:Being Alt Az, you likely don't have any issues with clearance and I doubt that the OP would have any issues because he is using a C9.25, but do you think it would have issues with the eyepeice holder hitting the lock knobs or the focuser on the EdgeHD 8" when used on a GEM?
“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Incorrigible ocularholic. Keep calm, and carry on observing.
Quote:I'm looking forward to your continuing reports.This though is why I recommended the Televue Short SCT to 2". I know it clears all the knobs on the EdgeHD 8" even with binoviewers and 31mm Nalger.It has compression ring clamping and is very solid with 31mm Nalger and even with Mark V Binowiewers or the Denk Binotrons used with heavy eyepeices.Have you tried rotating yours yet just to see? I would love to know if the eyepiece holder clears. My bet is that it does not, but I am sure there would be people that would like to know.The TV Short works though, and is about as short at you can get with a 2" visual back on the EdgeHD 8".
