FZS Hi there are some ways to remove the bright and subtle satellite trails in your Seestar photo. Subtle trail is difficult to remove because they are very close to the background sky value. See below for the result of using iOS 18.0 Photo>Clean feature and AstroEdit>AI>Satellite.

iOS 18.0 Photo Clean feature can easily remove bight satellite line. For very subtile trail, you will have to use your finger to swipe along the subtle line. It is fast and easy. The only con is that it removes also the stars along the line and generate new star. See the added blue star in the middle photo at the lower left line.
AstroEdit (iOs and android) AI Satellite removes both the bright and subtle trails. It uses a slider to allow user to control how much to remove. It keeps the stars on the line. The only con is that it has a small fee.
Hope you find the mobile solution useful!
