Firstly I noticed horizontal patterns the result after last imaging session. I checked darks - there were same patterns. But I didn't notice the same in my previous attempts. I tried to figure out the cause, probably cables or anything. But everything was the same. So I suspected the issue is stellarmate because NINA did have that issues with the same exposure and temperature

So I installed astroberry that I had. It was rather old version from spring. There were no such issues! (but it crashed a lot with my RisingCam IMX571). I tried CCDCiel - no issues. Then I upgraded astroberry and got banding both in kstars and ccdciel

So I installed old version of stellarmate 1.7.2 on another sdcard and did not have same issue. So I upgraded the same sdcard and got the issue. My conclusion that some update to stellarmate/indi causes banding on the same setup. It is not driver/sdk issue since they are of the same version

PS That's how I lost several days of my life and so rare imaging session.
