I have now collected the colour and luminance data for this image.
Combining all the data was interesting. I used Marco's method of overlaying the Ha, OIII and SII and assigning them to various colours and saturation. I think this works ok. I went for the more traditional natural colour than exploring the Hubble palette. I have done that to death on several images before of this object and never really liked the effect.
A few small tweaks on this system and it is going to work well I think. Very happy with the performance so far on this AG12. Another test image is being undertaken tonight of a dusty area.
