Hi Murray, Nice work on the image - well composed and a good result from your LP location.
Leaving colour palette aside for a moment, there's something weird going on the core of your M8 - it looks overly smoothed and lacks detail and contrast.
This is odd because you have spectacular detail in all the dark whispy areas between the trio, which is awesome. May be worth revisiting processing with a mask or two over the core area.
As to colour palatte issues, Mike (Placidus) has posted a very good insight into the inherent problems with NB imaging and the lack of signal in certain wavelengths.
There are many ways around this, but as Mike says, the best result is to gather bucketloads more S2 data in this case as the Ha can easily overpower the others.
Some targets eg: NGC 6357 aka "The Lobster" are very weak in O3.

Thanks for the nice feedback - for what it's worth, I use a variation of this method in PS

Followed by selective colour to taste -

I'm not a fan of "true Hubble" green dominated images, and will happily push established boundaries in pursuit of aesthetics - but each to their own.
And as we're all still learning, keep going and keep 'em coming :
