Past 5 to 10% in blue channel to simulate H beta and flatten all when happy with blend , merge RGB again whilst in PS.
Check color bias,will shift so normalize.
This will retain your normal looking stars but experiment because depending on how much Ha to how over powering It might be.
Stretch you new HaRGB to prepare It for the luminance then stretch luminance but don't brighten too much(that's why LRGB combine works well in AA) then paste onto HaRGB.
There's is nothing wrong with creating a "Super Luminance" using L & Ha,so try It as another layering.....remember keep brightness down to combine to RGB,
I sometimes find that I get better results with multiple Luminance layering with low opacity and slightly increasing each time(ala Rob Gendler LLRGB)
Good luck!

Thanks for the tip - I will try a re-process when I get a few hours to spare...
