This is my first real attempt at post-processing. Stacked in DSS, then Photoshop.
Canon 40D, ISO 400, f/4, 75 seconds - stack of 120 images
I'm still really disappointed with the colour gradients and the colours in the final image.
The first time I stacked them I included the flats I'd taken, but ended up with a much darker patch halfway up the left side of the frame, so I stacked them again and ended up with what you see here.
Shouldn't flats take care of problems like vignetting, etc.? Or are they more to just eliminate dust spots in telescopes? (There's also a very good chance I didn't do them correctly - it was my first set of flats).
This was taken on a pretty dark, moonless night where I live. Without a sky pollution filter in this the best I can hope to do in terms of H-alpha? You can just start to see Barnard's Loop coming through. It would probbaly be easier to see without all the terrible and funky darks/lights/funky colours...
