I understand that hosting isn't the best place to discuss an image, but you didn't post this work on Astroforum. I wanted to critique and offer advice, but I'll refrain because there isn't enough information for an objective evaluation. Is this a single frame, or processed from a series? Please provide COMPLETE information: exposure, gain, number of frames, shooting location, etc., etc...
At first glance: you didn't monitor the histogram during shooting (overexposed), out of focus...
