This is 10 hours of Luminance data with the QHY9. I think the weather is going to be pretty bad for a while, so it may be a while before I get any colour!
Might give me a bit of time to sort out the issue with the cooler!
I forgot to tick the Clamp box in the settings! It produces shadows behind bright stars. It's not really noticeable. Any ideas how to process them out?
