As you say mosaics can be tough, did you have any problems with gradients?

Hi Justin. Yes I did have some gradients. I corrected for excess green (there must have been airglow that night) and normalised the backgrounds before I stitched them. I also did a gradient correction although by that stage gradients weren't too bad. The main issue was one panel was taken at an earlier date to the other 3 which is not good procedure as I decided to do a mosaic later on after the first image of the Neb.
