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!
