Description

NGC6781 is a nice planetary nebula in Aquila, a few thousand light years away. There is a real story behind the processing on this one, including combining HA, Luminance, and OIII as the color channels, using L for Green. Yeah, kind of a different technique, but I was happy with the overall outcome. That and fixing the stars from horrible flexure which I did not take time to try and correct, I just did all the corrections in postprocessing. Not the way I would recommend!
