Hi,

I am after ways to improve my HaRGB stacking ability. This was taken with my W/O Flt 110 and consists of 3 hours Ha at 10 minute subs with darks and flats applied to all. Then 1 hour of each RGB. Camera was QHY-9 mono at -20c. I googled and found Color Imaging of Nebulae using Hydrogen-Alpha Data by: Robert Gendler.
I processed Ha, R, G, B and then stacked the Ha on top of the red layer and set the opacity to 50%. Then I flattened this combination and made an Ha/R with G and B. then I coloured balanced as best as I could but found the Ha/R histogram was huge and broad compared to the G and B. I then did some curves and levels with some other basic colour adjustments.
It is my best Rosette and am happy but am always keen for advice.

Thanks.

Mark
