I don't use my F/3.3 much even with my ST7 because of distortion & vinyetting. Definitely not recommended for a larger chip than that of a ST7/webcam.

My situation is perhaps worse than the norm becuase I havea focuser in the mix, moving the focal reducer further from the mirror and exadurating the problems.
