IC 2391 (also known as the Omicron Velorum Cluster or Caldwell 85) is an open cluster in the constellation Vela consisting of hot, young, blueish stars, some of which binaries and one of which is a quadruple. Persian astronomer A. a.-R. al-Sufi first described it as “a nebulous star” in c. 964. It was re-found by Abbe Lacaille and cataloged as Lac II 5.
