For some reason I can't reply to your message, maybe because I am not a Pier 5 member. I see the bands you are talking about. Suggest going through the uncalibrated subs and see if any have clouds. And the clouds could be thin so have to look for star bloating. If no clouds then could be an issue with the flats over correcting."
Thanks Daniel. I will check out all the subs. I did not spot anything obvious with Blink, but I may have missed something.
Overcorrectiion with the flats would be a concern as the flats are all fresh.
