Hey..this is my first post..not even sure if this is in the correct forum..But if not im sure someone will direct me in the right direction...

I have a Sony DSC-717 digital camera..and im attempting to take photographs of the night sky..stars moon...yadda yadda. Ive been trying to get some 30 second exposure shots of the stars..and all the pictures ive taken always end up a little grainy or instead of the background being a nice black, its slightly red and fuzzy. The moon has been pretty bright the past few nights...Does this have anything to do with the red fuzzyness? I know long exposure shots dont work very well with the moon. If anyone knows anything about the camera, or how/if I can get this to work out nicer, ide appreciate any help. Thanks a bunch.
