M82. The Cigar Galaxy
The prototype of the starburst galaxies.
Discovered by Johann Elert Bode in 1774, M82 is located approximately 12 million light-years away from Earth in the constellation Ursa Major.
With an apparent dimension of 9x4 arc min and visual brightness of 8.4 mag It can easily be observed with a small telescope less than one degree apart from its close -and disturbing- companion Galaxy M81.
Narrow band and broadband data from NOAO Survey Programs 2012B-0201 and 2014B-0176 were combined to create this portrait.
In the original light frames, the field sourrounding the bright star adjacent to the galaxy was affected by a big streaking artifact due to satturated pixels in the CCD. I arbitrarily cloned this area to my own taste with nearby pixels.
