The attached effort has a different history. Using AstroPixel Processsor, I stacked the subs and extracted the Ha and OIII channels So I then went to ST (1.8) with 3 images - a RGB composite, the Ha and OIII monos from APP. The Ha was mapped to Red and the OIII to Blue. The RGB was mapped to Luminance.
From there I followed the workflow you very generously published here a few months ago that worked so well on the Tarantula.
As you will see from the "new" image, it is much more subdued but the colours still aren't right.
This brings me to the problem I continue to have with ST when it comes to the "colour" module. They are muted and lack punch. The red is more an ochre and the Blue - well my wife insists on calling it taupe - whatever that is. I used the sliders in ST to adjust the red,green,blue channels but it doesn't seem to bring out true reds, greens or blues. They are pastel approximations of the colours they should be. No doubt it's my lack of technique causing it.

Peter,
Startools is a actively tracking signal processor ( unlike traditional processing where you tweak each process but the previous process doesn’t know what you’ve done to optimise the current process ) Startools tracks both inputs , outputs from each module and knows exactly what’s happening ( evolution tracking )
When you use data from other software processes and jump anywhere into Startools, it has no evolution history of what you’ve done previously or what you want to do when applying the first process
I’ve seen on other forums folk using traditional processing software with Startools but end with a mess and can’t understand why. It’s a completely different way of processing
Startools should be used autonomously !!!
As far as colour goes , yes I agree it’s not easy to achieve the “psychedelic way out Pop Art” colours of Pi or APP or PS mostly using Narrowband but Startools takes a scientific approach to true colour spectrum of celestial objects. With broadband data , the colour module in Startools is excellent !!! especially in galaxies , can’t beat it
I have learnt to get pretty close to the “Pop Art” look in Narrowband but now prefer the natural colour of the various wavelengths in Ha , Hb , Oiii and Sii
Don’t give up on the Colour module it can work for you , there are plenty of options and variables to use
Cheers
Martin
(but of course, not as feature rich).
