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

Introduction | Map | Sketch | 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 is the main galaxy of a galaxy group in Ursa Major / Great Bear, which also includes the M 82 galaxy. Only in a small telescope, the two can be observed together, because the viewing angle should, according to Stoyan, be at least 1.5°. M 81 is a spiral galaxy, which is seen from above, whereas M 82 is an irregular galaxy, which is seen in edge position.

M 81/ M 82
Size: 12' x 5' / 6' x 2' (Stoyan/Karkoschka)
Distance: 11 million light years
Rating: **** / **** (Stoyan)

My Own Observations

Observations February/March 2017

On March 2, I looked out for the Bode galaxies M 81 and M 82, using the Heritage P130 telescope on the GoTo mount. This way, I was fairly certain that I would have them in my view. Whether I would be able to see them was, of course, open... Actually, I was able to see both of them very faintly. M 81, that is, the galaxy at which one looks from above, was a little bit easier to recognize.

Without the GoTo mount, I probably would never have found the galaxies...
