Maxim flats - the gory details
So here are a few shots to show you what I am wrestling with.
The first is an uncalibrated 5 minute image. It is a median combine of 10 images with a median combine. I have used the default auto-stretch in Maxim. Yes, I know there is heaps of dust about!
The second is a master flat taken through a green filter. Same deal with the stretch.
The third is after calibration.
Hope you can see my dilemma. Comments happily accepted.
