The Ha is always the best isn't it? I loved the initial Ha subs of this and kept shooting to trying and get other colors half as good. I ended up with 281 ten minute subs of:

Ha 67, OIII 83, Sii 53, R 27, G 26, B 25
All subs were binned 2x2 and unguided. Image scale binned is 1.44 a-s.

I first blended the Blue and OII 50/50, then the Red and SII 50/50. Those two were blended with Green for half of the Synthetic Luminance with the other half being the Ha. So the beautiful Ha was only used for part of the Luminance and not at all in the color channels.

Pretty sure I'm not done trying to figure out the right way to put this together but it is good processing experience!
