Albireo Beta Cygni

Albireo  is a binary star designated Beta Cygni (β Cygni, abbreviated Beta Cyg, β Cyg).
Beta Cygni is about 420 light-years away from the Sun. When viewed with the naked eye, Albireo appears to be a single star. However, in a telescope it resolves into a double star consisting of β Cygni A (amber, apparent magnitude 3.1), and β Cygni B (blue-green, apparent magnitude 5.1).Separated by 35 seconds of arc, the two components provide one of the best contrasting double stars in the sky due to their different colors.
