Can You Find Perseus?

Perseus the slayer of Cetus is most easily seen rising in the East in the winter. The constellation is most easily identifiable as what almost appears to be a wishbone of brightest stars, with the brightest being the center and chest of Perseus. The legs of Perseus are pointing southward and are the forked part of the wishbone and the body and head are the straight line leading up northward. It is easy to find Perseus by either looking southward from Cassiopeia or just to the left of Taurus the Bull.
