Messier 101 with a Type II Supernova
This is Messier 101 with a Type II Supernova. It was captured on May 25th 2023. I used a Celestron Edge HD 925 with a 0.7 reducer, an ASI 2600MC Pro. I managed to get 2 hours, 50 minutes total exposure time, with 34 x 300s subs. I processed it in Siril, Starnet and GIMP.
