Description

Imaging from the city is tough, I can get plenty of Ha data easily, but no matter how hard I try, the RGB data comes back sorely lacking. I do what I can in processing to use the Ha to provide some detail and structure, and then use the RGB mainly for star color. Ha also is used to boost the red channel. The final image comes out OK, I had to fight a lot of chromatic noise that kept creeping in.
