NGC 3532, also known as the Wishing Well Cluster, is an open cluster in the constellation Carina. It got the name because through a telescope's eyepiece it appears like dozens of silver coins twinkling at the bottom of a wishing well.

About 1,321^[2] light years distant and consisting of approximately 150 stars of 7th magnitude & fainter, NCG 3532 was the first target ever observed by the Hubble Space Telescope on May 20, 1990. Mimosa (Beta Crucis) & Delcrux (Delta Crucis) in the Southern Cross roughly point to NCG 3532 and it lies between the Southern Cross constellation and larger but fainter “False Cross” asterism with X Carinae the nearest star right next to the cluster but not a member and Eta Carinae & its famous nebula not too far away along with a bunch of other nearby deep sky objects. (3372, 3293 & I.2581.)
