I used to use a 72mm Tak FS102 F6 reducer on my RCOS 12.5 inch and it worked quite well. I used to get some elongated stars in the corners of an STL11 camera.
So depending on the size of chip it would be fine. Anything up to DSLR size I reckon would be OK.

I love the scope and all I want to get now is a suitable focal reducer and so if anyone knows of one that will work for an RC scope, please let me know. 
It's great at F8 but if I can also get it down to around F6 then I'd have it all
