Melotte 25 (Mel 25) - Hyades

Introduction | Map | Find/Identify | My Own Photos | Own Observations | References

On this page I collect my observations of the open star cluster Mel 25 (Hyades) in the constellation Taurus/Bull.

 

Introduction

I have only learned more about the Hyades (Mel 25) in the Taurus/Bull this winter (2016/17). They roughly form a triangle, which helps you to orient yourself. In February, for example, you can find them by starting from the Pleiades and continuing a little to the left until you reach a conspicuously yellow star. This is Aldebaran in the Taurus/Bull, which limits the base of the Hyades triangle on the left. You can then proceed to the right to the right tip of the triangle and follow the other side again to the upper left. The Hyades (5° x 4°) just fit into the field of view of opera glasses, I read (I do not own any ...), and can therefore not be seen completely in my telescopes and binoculars.

Size: 5° x 4° (Stoyan)
Distance: 150 light years
Ranking: *** (Stoyan)

Find/Identify

Find: The Hyades roughly form a triangle, which helps you to orient yourself. In February, for example, you can find them by starting from the Pleiades and continuing a little to the left until you reach a conspicuously yellow star. This is Aldebaran in the constellation Taurus/Bull, which limits the base of the Hyades triangle on the left. You can then proceed to the right to the right tip of the triangle and follow the other side again to the upper left.

Identify: If one has found the Hyades in the described way, one can be sure that it is the Hyades!
