This
            extremely dense field which is looking in the direction of the
            very center of our Milky Way galaxy reveals a bright star cluster
            in the center of the field - NGC6520 accompanied on its right
            by an inky black cloud of silicate dust cataloged as Barnard
            86. To its left is the extremely dust dimmed globular cluster
            Djorg 3, and on the right side a similarly dimmed globular cluster
            is Djorg 2. Ive included a photo key below the main image to
            show you where these are located. In addition, a very small planetary
            nebula is on the lower left corner M1-37 which shows here as
            a tiny pink disk.
