C90 Mak Thread Confusion

[Alien 13]

I recently purchased a Celestron C90 Mak and what a nice scope it is too it is also much bigger than I imagined.

My main reason for getting this scope is for full frame Lunar work with the Canon DSLR, the scope has a T thread on the end of the eyepiece holder but the thumbscrews get in the way a bit so I went and bought this http://www.firstlightoptics.com/adapters/celestron-maksutov-t-adapter.html but it unfortunately doesnt fit.

The thread on the scope is obviously smaller than an SCT as with this adapter http://www.firstlightoptics.com/adapters/celestron-sct-t-adapter.html but I cant realy find much info on it and what adapters would work.

Anyone got any ideas.

FLO did/used to sell this scope have they been able to help you with which adaptor?

Enjoy your new acquisition. Bet the Moon will look really nice.

Erm take out the thumb screws when using your camera , your eos adapter should screw then , that's what I do with mine and it seems to fit and work fine. Hope this helps.

Oops nearly forgot then jus put a think rubber band around to cover the holes were the thumb screws were on the eyepeice holder.

Having looked some more it seems like the best option I had wondered if an alternative might improve the mild vignetting with a DSLR but some experiments with differing spacings and mirror positions changed it very little.

Thanks for the replies folks.
