Hi Hobbit,
Do you have any sample data to show what you mean? Or is this related to my NGC6188 post? I am reading this thread with quite some interest as I also struggle to align images, however +1 for Fred's comment. I find it *much* easier to edit the NB data separately and then RGB combine in PS (along with spot re-touching).
If only I could work out how to align between editing the NB channels and then RGB-combine in PS. Would CCDstack be the best option?
