Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy about 12 million light-years away in the constellation Ursa Major. It is about five times more luminous than the whole Milky Way and one hundred times more luminous than our galaxy's center. The starburst activity is thought to be triggered by interaction with neighboring galaxy M81. You can see the distrubance in the galaxy as red streamers above and below the main galaxy core. This image was taken over several nights in April, ending April 18th, 2015. It is 7.5 hours of exposure through RGB, luminance and an H-alpha filter to bring out the red starburst. The camera was an SBIG STF8300m which I am just getting familiar with. Click on the image for a larger view.
