focal reducer for GSO RC8?
Does anybody use a reducer on a GSO Rc 8?
If so which one and is it any good?
What spacings does you use with the camera?
I am interested in the Astro Physics on on the Teleskop_Servic website but would appreciate any thoughts
Would be using it with a QSI 683 and or a DSLR.
Cheers
Graham
