Description

The goal was to show some of the outer shell. I was going to blend the Ha channel with L but the L channel had some weird issue with oblong stars on the edge of the field so I didn't use it. I could have used big longer RGB exposures to bring out some of the colors in the outer shell. Ha 16x600m, RGB 10x150s 2x2 binned.
