Hi Ewald,
can you share a selection of images with me (raw frames, flat frame, dark frame) in FITS format please so that I can try to reproduce the issue as you see it. I'm afraid I do not understand quite what is going on yet
cheers,
Robin
Yes I have to do them but no problem. I will do next possible night!

I tried to do some testfiles for you.
Here is a
link to ZIP Archive: sharpcap.zip
There are three directories
- screenshot1.jpg (16.55 KiB) Viewed 530 times
In "Capture" you will find the flats I did with capture and substract dark flat frames and I used this night
In NGC6946 you will find the files I did with the above flats and the dark option hot pixel remove
- screenshot2.jpg (51.13 KiB) Viewed 530 times
In IC5070 you will find one JPG which shows, that the flats above worked in combination with "real" darkfiles without any claim. I missed to save fits here.
- screenshot3.jpg (34.95 KiB) Viewed 530 times
I hope this files help you to understand what's going on. In case you need additional information or I should save the files different or other files, don't hesitate to tell me what I should (re-) do that it will be helpfully for you.

Hi Ewald,
unfortunately the zip file doesn't contain any raw frames (frames from the camera without any processing applied), so I cannot recreate the setup that you have to try to work out what is going wrong. You would need to switch on the 'save raw frames' option in live stacking to save these if you haven't turned it on already - see
https://docs.sharpcap.co.uk/4.0/#Controls%20Group
cheers,
Robin
