I decided to redo the M20 I recently posted. As I mentioned in my explanation I was not happy with the stars because the camera produced huge blooms which I repaired but that created noise and artifacts. I resolved this by reshooting the red, green and blue channels with 6, 30 second exposures each. I replaced the most offensive stars with the new ones without blooms and touched up the image. I am really happy with these results. To me it was definitely worth the extra few minutes.
