The Bubble Nebula - HαRGB Palette

The Bubble Nebula is a favourite amongst many astrophotographers, and I'm no exception. This wonderful object can be found in the constellation Cassiopeia. The apparent bubble that gives this nebula its colliquial name is caused by the stellar wind of the bright, hot central star clearing the space around itself. It lies inside a giant molecular cloud, causing it to glow. But the expanding bubble of "clear space" around the star is what gives the appearance of a large soap bubble in space.

 

I've shot this target before, but never in the current palette, which combines a session of RGB data along with a session of Ha.
