Description

Sh2-157, as designated in the Sharpless Catalog, is an emission nebula located in the constellation Cassiopeia approximately 8,000 light-years distant.  It is only a short distance from the famous Bubble Nebula.  The small bright nebular object at the base of the "blue pincher" is designated Sharpless 157a. It is a nebula surrounding the Wolf Raynet star WR-157.

Shot over 3 nights in my Bortle 5 backyard.
A SHO image using a blend of R=0.5SII+0.5Ha, G=0.5Ha+0.5OIII, B=OIII
The stars are RGB.
Standard processing with HDR enhancement, sharpening, deconvolution, star removal with Starnet v2 and RGB stars added back in, denoise, and some touchup in image editor.

Hope you enjoy.
Clear Skies!
