Description

This is about 3.5 hours of data. The background stars are from 1.5 hours of RGB data. M57 is the RGB data with 2h 5m of H-alpha and OIII as a 45% opacity layer on top of it. I used three concentric masks, and the outermost ring of H-alpha was processed separately. The inset is the H-alpha channel as a monochrome image.
