NGC884
I decided to take this image of the open star cluster NGC884 with the goal of practicing my star field processing technique Basically, I think my star field images can be improved mainly in the sense of getting better colour into the core of the stars.
For this image I tried several different approaches before settling on a DDP stretch of the Lum and RGB data which I then blended via PS Screen with some slightly stretched linear RGB data to get colour into the star cores.
I set the exposure at 120s which gave a result such that the pixel level was just below my cameras non-linear region for the bright stars.
LIGHTS: R:20,G:20;B:12 x 120s, FLATS:30, BIAS:100, DARKS:40 all at -20C.
