Nice image Roger.
I have used your sub times to take my own image. Probably due to filter densities my colours was different, but now I have a starting point.
First time I have done binned RGB. Works well.
I also have a problem with dark blotches on the ST7e images. Flatfields don't seem to help, I'll try some bias tonight
. Do you have this problem? How do you overcome it?
