Description

These galaxies are a bit out of my reach since they are quite small in the FOV. I tried anyway since I always liked the arrangement. More data with an additional night would have helped with background noise, but that probably won't happen. It was a fun project anyway and the image is not too bad. Some details within NGC 7331 can be seen and Stephan's Quintet is ... well ... it's there :-)
