The scope has virtually no vignetting. Although I probably should apply darks. Bias are not very workable with CMOS so I tend to stay away from them -even flat darks seem touchy. CCDs work well with calibration in comparison.

Thanks Greg,
it's hard to know if you could squeeze some extra quality out of your images
by applying: darks, flats and bias frames.
It's been a matter of great controversy for many years now as per here:

I suppose all you can do is try it and see if it's any better?
It would also depend on your stacking algorithm.
Your results are very impressive without all that mucking around.
cheers
