This is my second attempt at this subject. Details:-200mm reflector, Canon 1100d modded, 20x120sec, darks, and bias, no flats (seem to make the picture worse.

Can easily make our the keyhole and that's the main part :D
How are the flats making the picture worse?

They seem to make the whole thing a lot "flatter" not so much resolution
