I own a vixen r200ss reflector, this is a 800 mm focal length scope with an f ratio of 4. I have had great widefield views, and success with a canon dslr. However, I cannot reach focus with my st-2000xm. It seems there is not sufficient back focus, meaning I cannot rack the drawtube in close enough. I do not want to change the focuser and do not know if this would completely resolve the problem, plus I do not want to change the coma corrector from stock. The only resolution from what I can see is cutting the OTA to force the light cone out of the drawtube. What are the draw backs of doing this? I wam wondering if you could advise me
thanks

How far are you from reaching focus? wouldn't moving the mirror forward be an easier solution?
