I have noticed artifacts that are quite apparent on Moon images (see attached). I used AutoStakkert to produce a TIF image from a SER sequence and afterwards sharpen it with Registax. This workflow seems to work fine for smaller planets, but on Moon images, four magenta rectangles are apparent. They always show up in the same spots.
Can these be avoided?
