Description

A small nebula in the Sharpless2 series. There are two objects are in the upper right corner and duller (97 and 151). Just below and right of the main target is LBN 154.

Processed with PI using the AIP NP script. H-alpha got about a 70% brightness rating rather than 50% and their noise reduction used.

All original images denoised with MUREdenoise individually.
