Description

Bubble-like nebulas are always fun targets to image, and this is one of the most well know examples. It was exciting to find lots of detail in all three narrowband channels.

Star removal in native photoshop alone this time. I noticed another photographer on this site (forgot who) that specified the narrowband colors in degrees of hue instead of RGB coefficients, which was a great hint for how to improve my post processing workflow. In this case I'm using Ha -> 12°, OIII -> 230°, SII -> 107°, which is a fancy way of saying HSO with a little mixing of green for all channels.
