First thing, I know the stars are pretty bad. Why do they look like little ghost? Is it the lens, tracking, camera or lens settings? To get them this small I downloaded a trial of APP and used the star reducer in the beta version. It looks like there are star artifacts in the image. But I think I need to solve my hardware problems before I try to improve my processing. Thanks for any and all advice.
