    Looks good to me, maybe have a look @ gradient removal, in Photoshop, or with IRIS (complicated), or a cool little tool for JPEGs, from Molecular Expressions (Background Subtraction tool, easy).

  1. Flats are easy to make, either at twilight, dawn or dusk, quick exposure (I use 1/250s for ISO 1600, and abt. 1/180s for ISO 800). Or put a white t-shirt or s/thing like that in front of the objective / entrance of scope )I wrapped it around some), shine a uniform lightsource at it (flashlight, cellphonelight, somewhat bright), and make the exposures w/ the cam to the scope (t-ring adapter, like making prime focus pics.)
