I wasn't real happy with the first rendition of the narrow band image I put up and judging by the number of comments I figure that many others did not really like either.
I tried Ken Crawfords tutorial on narrowband clipping which woudl work really well on many other objects except this one. The SII data in this object and region is pretty low and that makes for blending challenges.
In the end I simply did combined two images to get on out. One with Ha mapped to green, OIII to red, SII to blue and then one with Ha to red OIII to green and SII to blue. This resulted in the stars looking better than before, and also the colour looking overall more pleasing.
