Description

Not real happy with how this turned out. I was hoping to get a nice clean luminance from the Ha, and fill in with RGB color data. Instead, I struggled with star size mismatch, low saturation on the LRGB (pink nebula), and lack of luminance detail in some of the reflection nebula areas.
