About this object

Sharpless 2-82, also known as the "Little Cocoon Nebula" is a red emission nebula surrounded by a faint blue reflection nebula. It's located within the Milky Way in the Constellation Sagitta. Sh2-82 is approximately 3,600 light years distant. The star causing it to glow is the HD321616 which is near center.
This is a rather short exposure for me totaling 8.8hrs with most of that coming from the HII filter. I think next season I'll add more to this. I also provided an
annotated image with a few more objects identified.
