Well I've reproed this image again. I think the problem was that I didn't have enough subs from the Astrofest, and PI wanted to use "percentile clipping" for thiose subs, while wanting "Windsorized Sigma Clipping" for the rest (changed from one then it would ask for the other).
The long and the short of it is that I dropped the subs from the Astrofest, which were only half a dozen or so 5 minute subs, and I seem to have been able to extract a bit more detail in the bright regions. Once again the colours seemed more natural to me, although I boosted the saturation a bit to deepen the emission nebula colour.
I think I'll rest on this repro until I get more data... maybe another dark weekend at Leyburn next month?
