M81 (left) & M82 (right) present a beautiful Astrophotography target. The two famous galaxies are situated in Ursa Major at a distance of 12 million light years from Earth. M81 shows tidal interaction from M82 at a distance of 150000 light years. The cigar shaped galaxy M82 is distorted by the gravitational interaction with M81 and shows strong H-alpha streamers in the direction of the rotational axis far out from the galactic plane.
