Messier 51 (M 51)

Introduction | Map | Sketch | My Own Observations | References

On this page I collect my observations of the galaxy M 51 (Whirlpool Galaxy) in the constallation Canes Venatici.

 

Introduction

The galaxy M 51 in the constellation Canes Venatici is also called Whirlpool galaxy. According to Karkoschka, it is easily visible with its bright core, but the long spiral arms are only faintly visible even in the telescope. A spiral arm winds to the galaxy NGC 5195 (see sketch by Michael Vlasov). Stoyan writes that there are two interacting galaxies: NGC 5194 and NGC 5195. He also writes that one can recognize changes of the famous spiral arm structure only with an opening from 8" upwards, and for a clear impression and the connection between the two galaxies even 12" are is required. No wonder that I could only see a glimmer and at best a bright core ...

Size: 8' x 4' (Stoyan)
Distance: 30,000,000 light years (Stoyan)
Rating: *** (Stoyan).

Sketch

The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I observed (my impression was much fainter than the sketch): Whirlpool Galaxy (Messier 51, NGC 5195) - Sketch by Michael Vlasov (Copyright © Michael Vlasov 2016)

My Own Observations

I approached M 51 in Mühlhausen / Kraichgau in mid-May 2017 with the Sky-Watcher Explorer 150PDS on the GoTo mount.
