M34 is a relatively unremarkable open cluster in the constellation Perseus. About 100 stars span more than the diameter of the full moon to make up this large cluster. M34 is visible to the naked eye on clear nights as a faint nebulous patch among an otherwise rather empty star field. It is most defined by the several sets of visual double stars that form pairings near the center of the cluster. M34 is about 1,400 light years away.
