A photo of M81 (or Bode Galaxy, on the left) and M82 (or Cigar Galaxy, on the right). There are two galaxies located about 12 million light years from Earth. It is estimated that the size of M81 is slightly lower than our Galaxy containing a number close to 250 billion stars. The interaction between the two galaxies led to the formation of hydrogen gas filaments, which were partially depleted on M82, and increased its star formation activity. Processing of 150 calibrated shots, obtained with Nikon D5100, SkyWatcher 150 / 750PDS and eq5 motorized equatorial mount.
