I have only 2-3 hours per clear night from my field of view, so I decided to skip SII filter for now. I have also tried to bring out the oxygen more in the core of the nebula and to have it more blue, but there wasn't enough oxygen data. So this is what I settled on in the end.

Comments & Feedback are appreciated!
