The background could use some work — there are colored spots, and in the upper right corner, something that looks like dust on the sensor. Do you use flats? I can't figure out what needs to be done to make the background so uneven.

I need to, but it doesn't always work out. I use flats, but with a corrector they are a problem. I don't even know why.
Well, either the background is uneven, or there are no stars :).
