Photo description / processing

IC 10 — a compact dwarf irregular galaxy in the constellation Cassiopeia and a member of the Local Group along with the Milky Way, Andromeda, and Triangulum. 
It is located approximately 2.3–2.5 million light-years from us and is known for its unusually intense star formation relative to its mass. 
A special feature of IC 10 is its rich population of Wolf–Rayet stars: these are extremely hot, massive, and short-lived stars that rapidly lose material in a powerful stellar wind. Their large number serves as evidence that massive stars were actively forming in the galaxy very recently — in the astronomical sense.

This object is rarely imaged by amateurs due to its difficulty for imaging — very low surface brightness, and it is further dimmed by interstellar absorption in the plane of the Milky Way, since it lies almost in the plane of our galaxy and is seen through a great deal of dust and stars.

Great result, excellent work. I've shot it too, an interesting object, but my capture time is several times shorter, I think I'll come back to it again.
