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.
M 81 is the main galaxy of a galaxy group in Ursa Major / Great
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.

Size: 12' x 5' / 6' x 2' (Stoyan/Karkoschka)
Distance: 11 million light years

My Own Observations
Observations February/March 2017
- March 2, 2017 (Mühlhausen/Kraichgau: Heritage
P130 on GoTo mount): Looked
out for the Bode galaxies M 81 and M 82 with the GoTo mount.
This way, I was fairly confident that I would have them in my view. Whether
I would be able to see them was, of course, an open question... 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... Without the GoTo mount,

Observations May 2017
- May 5, 2017 (Mühlhausen/Kraichgau: Explorer
150PDS on GoTo mount): M
81 observed, faint (moonlight was disturbing)
- May 14, 2017 (ditto): M
81 quite well to see
- May 15, 16, 2017 (ditto): M 81/82 quite well to see, this
time even both galaxies (left: flat, right oblique)
Observations September 2017
- Sep 21, 2017 (Sumène, Haute Loire, France: Heritage
100P): M 81/82 (Bode
Galaxies) observed at various magnifications (eyepieces: 24 mm, 16 mm, 7
mm, 4 mm); both(!) galaxies seen well, even the one that is looked at from
the side. This time, I found the galaxies without a GoTo mount!
