Description

A closer view of NGC 6946, the Fireworks Galaxy, which I imaged last year as a wide field with the nearby cluster NGC 6939. NGC 6946 is a starburst galaxy about 7.7 Mpc away on the border between Cygnus and Cepheus. Ten supernovae have been observed in it since 1917, which on a per-unit-stellar-mass basis is about 20x the rate in the Milky Way. As this field lies near the plane of our Galaxy, there are many foreground stars to deal with.
