youve come a long way zuts..... spent a lot too
there looks like a gradient accross the image.... im fortunate not to have to much city light pollution, but maybee get hold of something to even it out.
Also a few motes that slipped past the flat field are evident, the program i use doesnt do particularly well with these..... but you can very selctively use the Dodge/Burn tool in photoshop to rectify these, just softly with a low pressure brush .
apart from those minor details a big improvement, its nice to look back and realize the achievements that have been made.
clive.
