This does need some more work (I say that about all my images if you haven't figured that out by now), the star color is kind of strange, sky is a weird gross color, and there is an ugly gradient on the right side...this was just a fast processing though.
Anyway, I tried working on a grayscale image where I did the cleaning, smoothing, sharpening, and all that usual adjustments. I then combined it with the RBG color frame and used the gray image as a luminance. Wow! More little detail shows up, and I didn't totally destroy it when screwing with the colors.
See the before and after images. These are both the same data taken on the same night.
