DescriptionThis was my first direct experience with capturing an "Arp Peculiar Galaxy" while participating in the Cloudy Nights EAA Forum October 2023 Challenge. I struggled mightily to find it, since I had not extended SharpCap's library to include the Arps, and the coordinates I found online were J2022, not the J2000 that SharpCap requires. Once I found the target, it was a straight forward capture, which I enjoyed immensely. It certainly shows two galaxies interacting. Most would say "merging" but I didn't appreciate the depths of that controversy at the time. Anyway, I fully enjoyed this observation and it predisposed me to take on the AL challenge when I learned about it a few months later.
