Description

Imaged from my red-zone driveway over 3 nights. This image uses Ha as a luminance channel, a blend of Ha and R as red, and wideband green and blue data. It's about 2 hours of Ha and about 4 hours of RGB exposure.

Only very modest boosts in saturation and contrast. I'm not sure I'm happy with the colors - I think the core is supposed to be more blue, but this is just what PixInsight's color calibration gave me. But I do like that the faint outer shell is starting to emerge.
