M 81 Bodes Galaxy LRGB
M 81 Also known as Bodes Nebula is a spiral galaxy located in Ursa Major. It is a close neighbour to M82 Cigar Galaxy in the same constellation.
M 81 was first discovered by Johann Elert Bode, who found it, along with M 82, in 1774.
M 81 is approximately 12 million light years from our galaxy and spans almost 70,000 light years.
A few hundred million years ago, a close encounter took place between M 81 and M 82, during which M 82 was dramatically deformed.
Imaged over 5 nights from my home in Gérgal, Spain.
