I’d have to read it more throughly, but the biggest annoyance with starlink is right after launch when they’re all clustered and super bright because they haven’t hit their normal positions. When you’re doing really long exposures, a satellite screaming through your field momentarily is easy enough to filter out those noisy frames.

Is light pollution from satellites great for earth based astronomy, no. Are they ruining astronomy like do much click bait leads you to believe, not in my opinion.
