I'm seeing some artifacts when taking flats with my ASI6200MM at high intensity (50% of range). I guess these are pixels that jump up hot to near 100% when the pixel gets near 50% filled for some reason. The question I have is that the pixels are surrounded by boxes in the captured fits images. Is the camera or camera driver creating these boxes for some reason? If so, under what conditions are these boxes created? Attaching image showing the boxes.
