Description

This image is a re-work of my Bubble Nebula data from 2017-2018 taken with the C11 Edge and the Orion 7 nm H-alpha filter. This image is a grayscale H-alpha version with a different workflow from my previous HOO version.

One significant difference here is the use of Topaz DeNoise AI , which can produce downright incredible results on the darker areas of H-alpha images, where the signal:noise is quite poor. Since this software tends to over-sharpen smaller stars, use of a star mask is essential. The settings I applied were: Remove Noise=21 and Enhance Sharpness = 1.
