I would be grateful for any help - complete newbie
Hi, I have just started my Astrophotography journey. I have done a couple of nights imaging and now I am working on the processing after purchasing APP. I have successfully processed public data on APP before but am having issues with meh own FITS images. When I go to analyse stars I keep getting the message in my attached screenshot. I have tried taking more flats different gain etc but I can't seem to work our the channel error. I weans even aware I was using differing channels for the light and flats. I am using sharp cap for capturing on Windows bootcamp.
I will be very grateful for any help.
Thank you so much for your feedback yes this was the issue and in hindsight seems like a very rookie error. Appreciate your help 🙏
