Messier 41: An Open Star Cluster in Canis Major

This is a shot of the Messier 41 open star cluster in the constellation Canis Major. Residing at 2,300 light years distant, the relatively small cluster of about 100 stars spans 25 light years in diameter. Under dark skies free of moonlight and light pollution, M41 is barely naked eye visible below the bright star, Sirius. I shot this at Frosty Drew Observatory in Charlestown, Rhode Island, USA
