Aveni-Hunter 1 and LDN534 Molecular Cloud
In Andromeda
with 10" f/3.9 Astrograph @ f/2.9
Uploaded 12/26/24

 

            
Here is a very rarely
            imaged target in Andromeda, the molecular cloud LDN534 with the
            splashy star cluster Aveni-Hunter 1 lying inside its birth cloud
            near the bottom of the nebulous streak. It is not entirely known
            what caused the cluster to form here, possibly a nearby supernova
            or wind from a hot blue supergiant nearby. None the less it is
            a perfect fit for our 2 degree wide field of our ten inch astrograph.
            See Sue French's Deep Sky Wonders book for more details.
