Qhy8 flats advice needed - M20
I finally got around to using my QHY8 last night and took 10x5min shots of M20 before the moon came up. I also used my new light box to do flats and took a series of 2 sec and 0.2 sec shots of flats to make master flats. I was pleased with the raw shots from the QHY8 but I totally messed up my flats as they didnt correct the dust or gradient in the image. This stopped me being able to process the image further.
Can someone give me a DETAILED explanation of how to use Nebulosity V2 to get a proper exposure for the flats using the QHY8 and then to then use them in DSS to correct the light image.
Thanks for your time. And Ive included the flat and processed image to see my problem.
All comments welcome as I sure need them
