OBJECT DESCRIPTION AND IMAGE SESSION

A bright and young open cluster in the constellation of Carina. It contains more than 100 stars. The brightest member is a red giant shining at magnitude 5. NGC 2516 is very easy to spot for the naked eye in darks locations. Since the cluster is rather big, binoculars tends to give the best view. Observers of binary stars will note that three fixed visual binaries are found in the cluster. All three have eighth-magnitude primaries and eighth- to ninth-magnitude companions. The Cluster was discovered by French Astronomer Abbe Lacaille in 1751-1752.

 

The object is located approximately at 1º 40' from reflection nebula IC 2220.
