The first time I targeted M81/82 was in April of 2022. At that time it was also my first time guiding, polar aligning and plate solving with an Asiair plus. I captured 30x120" subs with a DSLR, stacked with DSS, processed with Siril and Gimp. Here is my most recent attempt with upgraded gear and processing.
Redcat 51, asi533mc pro (gain 101, -10C cooled), Star adventure 2i, Asiair plus, guided, EAF.
Optolong L-pro, Bortle 5, 51x300" subs, Calibration frames; darks, flats, bias, Bortle 5.
Stacked and processed in Pixinisight.
