This has been a bit of a struggle. After several attempts to produce an image using Hubble Pallette and some other ideas, I ended up trying a bi colour approach. Discarded the SII data and mapped Ha to red and OIII to both blue and green. Calibration, stacking, cropping, noise reduction with Multiscale Linear Transform and colour combination in Pixinsight. Final colour adjustments and a high pass filter in PS. Still far from 100% happy but so far the best I have able to do with this tricky object.
