Description: A very beautiful and rich open cluster which consists of several star-patches and empty darker areas. There is a bright ~8 mag leading star little bit to the east from the cluster's apparent center. A long string of faint stars lie on the east edge whereas the main part of stars lies on the center and western side. Dark structures between star-groups are very complicated with averted vision.
