Exposures: 80 min each of LRGB in 10 min subs for a total of 320 minutes.
M82 (also known as the Cigar Galaxy) is a prototypical example of a starburst galaxy and is the closest of this type to earth. Supernova 2014J was discovered in the galaxy on 21 January 2014. M82's unique bipolar outflow is fueled by energy released by supernovae within the clumps at the core of the galaxy which occur at a rate of about one every ten years (Wikipedia)
The bipolar outflow of hydrogen observed with long exposures makes this an interesting target to image.
