Uploaded 9/4/21

 
This
            amazing nebulosity lies within 10 degrees of the more famous
            Dumbell Nebula, and consists of a bright open cluster of 7th
            magnitude that covers 12 arcminutes. Surrounding this nice cluster
            is the emission nebula Sharpless 2-86. Beautiful dark dust lanes,
            and Bok globules are contained in this object making for a very
            active field.
