M82 or the Sigar Galaxy is a galaxy about 12 million light years away in the constellation of Ursa Major. This galaxy is part of the M81 group, a group of galaxies that are about 3.6 megaparsec away from Earth. This group is one of the nearest galaxy groups to our own Local Group and is just like the Local Group member of the Virgo Supercluster.
The plumes of glowing Hydrogen that blast of the central nucleus are a consequence of the tidal forces inhibited by the interaction with its close neighbour M81. The sigar like shape is filled with large clusters of stars. This increased star formation is another direct consequence of the tidal encounters with M81.
The image was taken with 11" Vixen VMC260 telescope and QSI583WSG camera on a Gemini G41 mount.
Exposure time was 17 hours in total. LRGBH 4:3:3:3:4 hours. H Alpha data was collected during full Moon.
All images were taken in 1x1 binning.
