Recently I did LRGB and HA of the Gabriela Mistral Nebula, since then I have edited the HA data acquired:

I am attempting numerous ways to do a HA and RGB combination. I've tried the NBRGBcombination script, which produced nice results, but the overwhelming red makes it a little difficult to saturate/edit the other colours without it looking too saturated in general.
I've played with various %'s of mixing the HA in with red, but would appreciate if someone has more pointers or tutorials I could work through.
But what I would really like is to use the HA as Lum. It improves the detail tremendously, but leaves the entire image looking too “salmon” coloured. Is it common to use HA in Lum?
Here is HA blended into the Red channel, as well as 80% blended into Lum:

I've not edited it much further than the new LRGBcombination as my blue stars do not look right
I've tried various things, like removing stars from the HA to blend with the Lum, or use the HA straightforward instead of Lum – but nothing seems quite right. It also seems to cause problems with my mid sized blue stars, that have more of a blue glow around them when using HA in Lum. (I've tried a MT on the Blue channel before combining but it made no real difference)
Or I could possibly have been staring at the screen for too long. I don't know what looks right anymore. I know there is possibly no absolute right or wrong way, but would appreciate if someone had any insight or advice on what I should try. :-\
Thanks!
