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

Uploaded 10/5/16

 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.
