Messier 97, The Owl Nebula
Over several nights with an almost full moon, I battled sketchy seeing and assembled enough frames to get a decent image of the Owl Nebula. This is a planetary nebula in the northern constellation Ursa Major, 2,030 light years away. I used a Celestron Edge HD 925 with a 0.7 reducer, an ASI 2600MC Pro, IDAS NBZ filter, all pointed by an iOptron CEM70 mount. I managed to get 7 hours 50 minutes total exposure time, with 47 x 600s subs. I processed it in Siril, Starnet and GIMP
