NotesA globular cluster in Sagitta, within the plane of the Milky Way Galaxy. M71 is notable for the loose arrangement of its stars; it is far less compact and distinctively globular than most clusters of its kind, and this fact meant that for many years M71 was mistakenly classified as an open star cluster.
