[QUOTE="wornish, post: 341033, member: 15434"] Looking at the settings you used for the image posted ISO 1600 and a 25 sec exposure at f/3.5 I can't see any hot pixels but there is considerable noise which is not uncommon at these kind of settings. I would keep the ISO below 800 if possible even lower. Also cover the eyepiece for the viewfinder as you do get light leaks from there. Have you tried talking multiple shots at say 10 secs each at ISO 400 and then stacking them? As Mike asks how much do you crop because you can reduce noise in down sizing the image. You can also get software that reduces noise as well but that starts to up the cost [/QUOTE]
