M81, ZWO ASI533, No Calibration

[lainev]

Galaxy M81, Bode's Galaxy, on 211027. Average transparency and average seeing. Bortle 6. ~43 minutes total integration of 11 second subs at 101 gain. No calibration frames. Normally I would use Darks, Flats, and Flat Darks. Celestron Nexstar Evolution 9.25, ZWO ASI533 camera, ZWO UV/IR Cut Filter, Celestron .63 Focal Reducer, CPWI for telescope control, and SharpCap for image capture. Image processed in Siril, Startools, and Gimp. I use Celestron StarSense for initial alignment (really works well for me), Celestron Electronic Focus Motor (eliminates scope shake when focusing). All of this is attached to an old Dell laptop. The laptop allows me to run the scope over WiFi from my home office.
