Messier 82, a galaxy in the constellation Ursa Major, was discovered by Johann Elert Bode in 1780. Today we know M82 is a starburst galaxy where a large number of new stars are being born. Large amounts of in-falling gas are excited by the newly formed stars and are responsible for the red Ha emissions Total exposure was 11.4 hours (137 x 5 min lights) taken with a 130 mm f/8 Astro-Physics refractor and SBIG ST 2000xcm CCD camera on an Astro-Physics 1200 mount.
