Description

M51 Whirlpool Galaxy in LRGBHa at -30C, ambient was about 0. Used QHY DSO gain and offset settings.
Clouds moved in when this was to start so I got less data than I wanted.
Got a craving for shrimp cocktail after processing.
If you stare at this for 30 minutes you will travel forward in time by about half an hour!
