Uploaded 5/24/25

 

            
This nebula which is
            designted officially as LBN7, is a dense knot in the Scorpius-Ophiuchus
            molecular cloud complex resembling a flying bat. Ive heard this
            one refered to as either the "Cosmic Bat" or "Flying
            Bat" nebula. Notice that nearly every star in this field
            is yellowed by the extensive interstellar reddening from the
            dust. A few small galaxies appear in the clearer spots.
