Description

I tried to provide high dynamic range using an ASI1600.

For that I used a different gains and HDR techniques and ... a lot of captures.

Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away, with at diameter of 90,000 light years, about half the size of the Milky Way, in the constellation Ursa Major. (right side of the image)

Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major.

M82 is being physically affected by its larger neighbor, the spiral M81. Tidal forces caused by gravity have deformed M82, a process that started about 100 million years ago.

Ignoring any difference in their respective distances from the Earth, the centers of M81 and M82 are visually separated by about 130,000 light-years.
