About the target
NGC 6946, (also known as the Fireworks Galaxy, Arp 29, and Caldwell 12), is anintermediate spiral galaxy about 18 million light-years away, in the constellations Cepheus and Cygnus. It was discovered by William Herschel on September 9, 1798. NGC 6946 is highly obscured by interstellar matter of the Milky Way galaxy, as it is quite close to the galactic plane. The diameter of the galaxy is approximately 40,000 light-years or just about a third of the size of the Milky Way.
