SH2-157 - The Claw in SHO - QHY533M

[FiveByEagle]

Sh2-157, as designated in the Sharpless Catalog, is an emission nebula located in the constellation Cassiopeia approximately 8,000 light-years distant. The small open cluster of stars located in the upper right of the image is designated NGC 7510 and lies approximately 11,400 light-years away.  The small bright nebular object just below the "blue left pincher" is designated Sharpless 157a. It is a nebula surrounding the Wolf Raynet star WR-157.
The image above was compiled from narrow band filtered exposures to create a mapped color depiction of the nebula.  The standard Hubble pallet of Sulfur-II mapped to red, Hydrogen-Alpha mapped to green, and Oxygen-3 mapped to blue was utilized for the image.  Processed in Pixinsight and Photoshop.
For this image, I traveled about 25 minutes from my house to a public park that has skies half the brightness of home, and imaged this for about 5.4 hours.
