NGC 6946 Fireworks Galaxy - Cepheus
NGC 6939 Open Cluster - Coma Berenices
The Fireworks Galaxy resides at a distance of 19 million light-years, compared to only a few thousand light years for the rich open cluster NGC 6939. Discovered by William Herschel in 1798, NGC 6946 is called the "Fireworks Galaxy" because so many supernovae have been spotted there. The Galaxy is 40,000 light-years across and is a nearly face-on SAB-type spiral galaxy. The 9.6 magnitude Galaxy is rather a small and distant target for a small telescope, but can be framed nicely with the star cluster in this wide field image.
