Processing was quite simple:
Drizzle Integration
Gradient removal
Photometeric Colour Calibration against G2V (normal colour calibration made 47 Tuc white)
RGBWorking Space
Luminance extraction
Deconvolution on synthetic luminance
Stretch both L & RGB
LRGB Combination
Saturation boost
Green bias removal
You are right Glen in that Ha will give sharper stars and it is an interesting thought for globular clusters, could be worth trying at some point when I’m using using my DSLR
Rick, with the linear data in the D810, most stars have pink cores but I haven’t found that to be an issue when stretching with the HistogramTransformation but it doesn’t work as well with MaskedStretch. I find that as the data is stretched and the PSF is drastically fattened the real star colour swamps the pink core.
I agree with you Mike and although I have heard of HSV in Photoshop I only know it as a car
