Hi all, I am going to try and do some imaging with my celestron 9.25 SCT. I have a ASI 174mc for planetary which I will also try to use as a guide camera and want to use an oag to cut out load and flexure. I was wondering what oag you may recommend. Thanks in advance.
The Lumicon one is pretty good - just tighten all six bolts really well to remove any slippage! It comes with a focal reducer than can be removed (I did as mine showed coma). I use it on a C9.25 with a Meade DSI II mono as the guide camera and a modded DSLR in a cool box as the imaging camera. Once it is all set up I find up to 30 minute subs are readily achievable.

Awesome thanks for the great info, and that sounds perfect as I want to use it on my 9.25" aswell. I tried a search but can't seem to find a store that sells them. Would you know of a link or something I can go into. Cheers.
A quick search reveals they may have stopped making these to go for slim line bodies - so check on astro sales / classified for a second hand one also; some dealers might still have unsold stock; they are a great unit!
what oag you may recommend. Thanks in advance.
