Messier 81/82 (M 81/82) - Bode Galaxies

Introduction | Map | Sketch | My Own Photos | My Own Observations | References

On this page I collect my observations of the Bode galaxies M 81/82 in the constellation Ursa Major.

 

Introduction

M 81 (Bode Galaxy) is the main galaxy of a galaxy group in Ursa Major / Great Bear, which also includes the M 82 galaxy (Cigar Galaxy) (sometimes both galaxies are called together Bode Galaxies; the were both discovered by Elert Bode). Only in a small telescope, the two can be observed together, because the viewing angle should, according to Stoyan, be at least 1.5° (I was able to observe both at once in 2019, see below). M 81 is a spiral galaxy, which is seen from above, whereas M 82 is an irregular galaxy, which is seen in edge position.
