NGC6659 widefield
I had my usual wrestle with PI to produce this
. It is a blend of RGB and Ha data. I used the NBRGB script in PI. I finished it off in Photoshop.
I collected a bit of Lum as well for this image but in the end just went with HaRGB. I read a stack of info on the net about combining Ha and RGB and whether Lum is worth collecting but reached no conclusion on that one. Any constructive feedback appreciated.
