Description

Each target has its own set of unique challenges associated with it, this target was no different. When I first saw images of Sh2-119, I thought it wouldn’t be a hard target to process, until I started working with the data. In particular, bringing out the very faint OIII signal in the center was a challenge along with the number of stars in the FOV. If you plan on imaging this target, imager beware, lol.

Clear Skies everyone and Happy New Year!
