My RASA had bad seagulls, i didn’t have ones like those few really bright ones. I couldn’t get the collimation exactly right, but I did get the seagulls to mostly go away. (Celestron fixed it completely).
Something to note, after Celestron repair, I then notice an issue with tilt from my ASI1600, so if you are seeing things a bit different, in different corners, it could be that too.
I will get a more precise collimation ... Changing the screws out for Bob’s knobs sure points to a collimating error being the root of the problem
