Hope it's OK to post a question here
I am working on a 6 panel mosaic of the Rho Ophiuchi cloud.
Each panel is taken on a seperate night in RGB made up of 30x5m subs each.
Channels processed seperatly, background extraction, deconvolution, denoise, histogram stretch then combined to make one panel.
I have 'stitched' two panels together as a test and there is a difference in hue (see attached preview).
Playing with the curves (before stitching) helps, but it is tedious and 'hit an miss'.
Any ideas?
