Hi, I was trying to shoot night sky - stars - with my G5 + 12-50mm lens. I see noise specks everywhere in the photo, and I can't figure out what is causing this. I would much appreciate if anyone has had this issue and would kindly direct me to resolve this. Here is one of the shots. Subscribe to see EXIF info for this image (if available) I have done similar shots before with E-PM2, and had no problem with it. Maybe I was lucky that time.
