I added a Sii filter set of integrations to this to see what would happen. I also toned down the use of HDR Muliscale Transformation... I think I over used it in the previous image.

Although I generally like more realistic colors, I tried a lot of different combinations on this one and although this has some crazy colors, I kind of like the image... But while I was doing the processing, the questions popped into my head about what would happen if I put a normal blue filtered set of data in the blue slot along with Ha for red and Oiii for green? Might have to try that and see.

I've got to solve the coma problem... I'll get there.
