The Coathanger Star Cluster - C399 in Cygnus
Orion 8" f/4 Astrograph

 
 A
            favorite asterism, this very loose cluster makes a perfect imaging
            target for wide field systems. Set in a very rich Milkyway field,
            the collection of both golden and blue stars set against a spray
            of fine diamond dust is unforgettable. This shot is 15 minutes
            total exposure with the 8" f/3.9 under a very dark sky.
