A "double binary", a multiple system near Vega in which we can already distinguish two components with our sharp eyes. In the binocular, these components are clearly distinguishable, brightnesses of 5.1mag and 5.4mag at a distance of 208", which, when observed with at least a 60 mm telescope and higher magnification, disintegrate into double stars (guides ε1 6.5mag and ε2 5.3mag). The mutual distance of one pair is 2.6", the other 2.3", and their orbital periods are determined to be 1 166 and 585 years, respectively. The distances are 162ly and 156ly.
