I found myself struggling a bit removing satellite streaks from my astrophotography. The best option that I found is to use the Healing brush tool in Photoshop, but this has the danger of removing stars as well.
Of course, you could only use the light frames without satellites for stacking, but this may not be an option in some cases.
Which steps can be taken during stacking (I use Deep Sky Stacker and Sequator), postprocessing and possibly shooting to remove satellites preferrably as easy as possible and automatic?
