Just so you have an idea of the field of view through a c9.25" with an F.63 reducer, here is an image of m42 taken with a sony nex5 at iso 12,800 , 30 seconds unguided exposure with the moon in the sky. No darks , no flats and only one "noisey" exposure.This has been resized to 24kb , it was originally a 14Mp image.
