This and the other image I commented on have the makings of good images. I do see a couple of things I would personally do differently. First, your image would be helped tremendously by raising the black point until the blacks were actually black or very nearly so. Second, you have gone pretty heavy on the noise reduction, given the flat regions a kind of plastic look. A little pixel level grain in a lunar image never hurt anybody and gives the image a more realistic feeling, as it provides a natural sort of dithering beyond the 8 bits that most of our displays are capable of showing. If the noise bothers you when you pixel peep, then reduce it sparingly, or if possible, just don't pixel peep. :O)
