With days of really good sseing, i did not try to image the sun, but concentrated on deepsky imaging. After month´s of fixing problems with my DIY setup I finally was able to take an image without problems. Almost, at least. My Kolari modified Sony A7R4 was set to compressed RAW and so PixInsigght could not read the files. So I converted them to TIFFs and it worked, but could not use the flats because the result was way overcorrected. So I used GradientXterminator and slight cropping to get rid of the vignetting....
