Albireo - Cygnus

On this page I collect my observations of the double star Albireo in the constellation Cygnus/Swan.

 

Introduction

The double star Albireo (beta Cygni) is the "head" star of the constellation Cygnus/Swan, and, according to Stoyan, it is held for the most beautiful double star by many observers. In any case, it is a prime example of this class. Albireo is supposed to be separated into two stars by binoculars (0.5 'apart), but I cannot confirm this. And only with a telescope you can see the difference between the colors of two stars: golden (to reddish) and azur blue.

Albireo is easy to find visually, as well as "manually" with the telescope. In the eVscope, it is hard to recognize as a double star.

Distance: 34.5" (Stoyan)
Distance: 400 light years (Stoyan)
Ranking: ***** (Stoyan)
