Albireo (β Cyg β Cygni Beta Cyg Beta Cygni) is the fifth brightest star in the constellation Cygnus. Although it has the Bayer designation beta it is fainter than Gamma Cygni Delta Cygni and Epsilon Cygni. Albireo appears to the naked eye to be a single star of magnitude 3 but through a telescope even low magnification views resolve it into a double star.
