I am interested in getting the Alan Gee Telecompressor, and would like to mount it using this Baader T Adapter (T-2 part #21). However, I also have the #2956220 SC / HD-Clicklock Eyepiece clamp for my Celestron SCT 9.25. I wonder if I can attach the Alan Gee to the T-2 Part #21 and then have the #2956220 Clicklock on top of it, to make it really easy to change from visual to astrophotography applications. What are additional components that I would need to reach focus with a ZWO ASI224MC Camera?

Thank you for your help!

Hello, I have the #2408160 adapter, is it equivalent to the #2958500B ultra-short adapter if I use only 2 parts on the 3? I’m looking to reduce 8mm of optical path for my camera.
Do you have a solution to achieve a T2 length of 28.35mm? This is the backfocus difference for the SCT EdgeHD 8 with and without the focal reducer. Perhaps you may add a new part in your catalogue as this telescope is popular (is it a simple t2 extension tube).
Regards

Can the T thread section be rotated relative to the SCT thread section and locked in any chosen orientation of the camera? There appears to be a locking screen (possibly even three of them) to do this but it is easy to misinterpret images on a web page.
