M 81 – Bode’s Galaxy
M 81 is a galaxy often photographed as a duo because it appears in the same field as M 82 (the Cigar galaxy) with smaller telescopes. It is relatively close to us at a distance of 12 million light years. It is also modest in size at 87,000 light years compared to our own galaxy (100,000 light years).
It is part of a group of around forty galaxies located in the constellation Ursa Major. Its location relatively close to the celestial pole means that it can be observed most of the year.
