It did say he was a photographer, not an astronomer.
Surely an astronomer would have software for this that would produce a more accurate picture.

An astronomer would presumably not erase the stars.

I was thinking the field of astronomy would need to survey the satellites, in order to make sure it doesn't interere with any of their observations of the stars.
So, they would erase the stars, but only to create a satellite mask, generally speaking.

Actually, this is pretty common for non-scientific astrophotography! Erase Stars -> Edit background and stars colour, contrast etc separately -> Recombine!

Why not? Stars are boring, the cool things are galaxies.

Perhaps ironically there are times when astronomers “erase” galaxies. Erasing things is routine to get at the things you want.
It then usually gives you an image of both the combined success, and an image of just those pixels that were rejected. So, this.
