Description

I captured the Horsehead Nebula IC434  in Dec 2022 with LRGB and Ha, Oiii,  the Ha data is very good, small star with nice nebulosity. Tested to generate color image with LRGB, LHaRGB, HOO, none can have nice nebulosity while having small stars in natural color and no heavy fringing. I did not take another look at the data until yesterday, when experimented with HaGG. There is still some blue fringing on the stars, but I am pretty ok with the result.

Edited: I recaptured the Oiii data and use the HOO palette as final, although the Oiii filter has halos, the overall stars looks better.
