Description

It was a long night! I started with the Andromeda Galaxy at 8:30pm, followed by the Pleiades at 11:15pm and then finally i tried M78 at 2:30am. Unfortunatly the temperature decreased and the focus changed (despite the pyrex mirror and the carbon tube) a bit what i didn't notice (how stupid). However, i decided to process the picture. Here is the result. I will definitely try that object again (with proper focus)!
