Experience and recording M81 / M82 with Askar 140 APO and ZWO ASI2600mm

Hello Mr. Kloss,
I'll report back with the first results. I am very satisfied with the quality, both mechanically and optically.
On Friday and Saturday I had clear skies in Schützen. I assembled everything and put it on the CEM70G with iOptron Pier at the factory. Despite the moon phase, I really wanted to record enough material so that I could publish it on astropolis.pl. Conditions on Friday were very severe as there were gusty winds (initially). On Saturday it was quieter, but with the moon already at 77% it was very disturbing. You can see the gradient in the recordings, but it can easily be combated with new tools.
All in all, I managed it :) After focusing, the tilt is almost imperceptible at 2-3% and the curvature is around 8-9%. All essential recording data below. I attach the edited image (in Pix) and a Lum Master. Individual lum recordings, if you are interested, I can also send later.
