OK, so I felt obliged to go a bit over the top and do something a little different since we had plenty of more traditional treatments
Using PixInsight: I blended the Ha and Oiii to make a Luminance. I mangled the Ha to red/orange tones using PixelMath and CIE Lch channel combination then used the Oiii as a mask and added some blue with CurvesTransformation. I stretched the Lum and colour, did a small star reduction and combined them. Then I tweaked the contrast a bit with LHE and HDRMT...
Cheers,
Rick.
