Messier 31 (M 31) - Andromeda Galaxy

Introduction | Map | Sketch | My Own Observations | References

On this page I collect my observations of the Andromeda galaxy M 31 in the constellation Andromeda.

 

Introduction

The Andromeda galaxy M 31 in constellation Andromeda (but it rather is located between the constellation of Andromeda and Cassiopeia), is our neighboring galaxy and about 2.5 million light years away from us. Because it can be seen with the naked eye under good conditions (in which I have never succeeded yet), it is the most remote sky object that we can see with the naked eye. It can be seen in binoculars and in small telescopes as a diffuse shimmering elongated oval - and I have not been able to detect any details yet, although one should actually recognize the two small galaxies M 32 (like a star) and M 110 in a small telescope. In other words, light pollution is quite high in Mühlhausen / Kraichgau ...

Sketch

The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I observed (my impression was much fainter than the sketch):
