Description:
Brightess member of the Pleiades. Superb quadruple star, the most beautiful that I ever observed with binoculars. All the components are quite split at 9x. The secondary star is quite visible just W of the primary star. The tertiary and quaternary star arise at NW of the secondary and forms a V with this one. Colors: primary star = white-yellow, secondary star = blue, tertiary and quaternary star = blue. Beautiful sight!
