Re: [APML] Need help processing NGC 7023

Alan, not sure I can help you fix it up but I can see from the histogram that the red and green
channels are quite clipped but the blue is most assuredly not. If you can go back to an earlier
version of the image and figure out when the red and green channels lost data, that would bring the
colours into better balance I think.
