Mainly because I hadn't a clue how to process Ha data

Your turn, now.

Technical query for you. How would this work when incorporating NB data into the image. You can seen in the RGB that NGC6303 is slightly orange yet it's response looks identical the Ha, OIII, and the one that isn't shown SII. When considering the image is truly more NB than it is real colour, how would different colours even come across? Certainly everything I did I did equally to both nebulas. The problem ultimately comes as soon as I apply Ha to the red channel. I had another image which was Ha+R, G, and B and even that looks like it already clobbered the orange shift of NGC6303.
