mount for a C9.25

Posted By Peter Webb

I just bought a used Celestron 9.25 OTA even though I couldn't really afford it. Now I need to come up with an inexpensive mount to use until I can afford to upgrade to something solid. Anyone have any thoughts on making do with an Orion Skywatcher Pro or a Synta EQ5 or the forthcoming Advanced Series EQ5 from Celestron? The folks at ITE told me not to bother with a cheap mount and that I needed a Losmandy G-11, but that's just not realistic for me. Any thoughts?---Peter

2in. or 1.25in. diagonal for my C.9.25?

Posted By Peter Webb

This is an issue that's covered a lot, but...It's time to upgrade the diagonal on my C9.25. Could someone review the pros and cons of 2in. versus 1.25in. diagonals for my SCT? Is it just a FOV issue? Thanks.

C9.25 fine focus issues

Posted By Peter Webb

I love my C9.25, but the stock focus knob (the new black rubber type) binds on the sides of the hole in the focuser cover. Plus it just isn't precise enough for fine focusing at even moderate magnification. I don't want to add a whole new crayford style focuser. What I want is a new focus knob, possible a two stage design with gross/fine focus options. Anyone have any suggestions or experiences to relate? Thanks!

Re: Anyone know what this 1.25 eyepiece is?

Thanks for your guess John. The upper part of the body is aluminum; the lower part does seem to be a heavy black plastic.

2" diagonal for a Celestron C5 ???

Posted By Peter Webb

Hi Tyler,

I have a Celestron G5, and I can use it with my Antares 2" SCT diagonal. It's tight, though. There's only about 4mm between the body of the diagonal and the focus knob so the diagonal can't be rotated into just any viewing position. The G5 will not work with my TV 2" SCT adapter (the non-removeable set screw hits the focus knob, though I could probably install it if I removed the focus knob, screwed the adapter into place then reinstalled the focus knob. Bottom line, I think most 2" SCT specific diagonals would screw on alright, but getting a 2" refractor style plus adapter to work might be more problematic. Hope this helps.
