NGC 3532 is a spectacular open cluster in the constellation Carina with an estimated age of 200-350 million years. Its popular name, the Wishing Well Cluster, comes from the resemblance of its stars to coins shimmering at the bottom of a Wishing Well. It lies only 3° from the remarkable star Eta Carinae and its associated nebula. NGC 3532 was first recorded by Nicolas Lacaille in 1752.
