The Pleiades (M45)
The Pleiades is the most famous of all open star clusters, containing around 500 members set against a black velvet sky. The young first magnitude open cluster is easily visible to the unaided eye and resembles a smaller version of the Big Dipper. At least six hot blue stars are readily visible and keen eyed observers can see more. Best seen in binoculars, this cluster is also called The Seven Sisters.
