Uploaded 9/20/24

 
The
            Scutum Star Cloud is certainly one of the most prominent and
            densest collections of stars in the Milky Way. Here, it occupies
            most of the center of this image which spans 3x2 degrees and
            appears as the finest star dust with gold and blue stars. On
            the left side is the magnificent star cluster M11, and on the
            right edge is the dark nebula Barnard 103. 

            Technical Data: 8" f/2 RASA, Baader UV/IR block filter,
            ASI2600 MC, 40 minutes exposure from Happy Jack, Az.
