| Description | This was one of the early observations after I took delivery of my EdgeHD 8", anxious to capture a closeup of M101 before the supernova faded. I started as early as possible on September 5, approximately 9 PM and captured 36 minutes, which is about the most I could as elevation was about to fall below my horizon. The big arm is evident although this pre-dated my interest in the Arp Peculiar Galaxies and was not a particular priority. |
