Description:
The Southern Beehive Cluster (because of its similarity to M44, the Beehive Cluster) a southern open cluster (http://en.wikipedia.org/wiki/Open_cluster) NGC 2516 AKA The Diamond Cluster was discovered by Abbe Lacaille (http://en.wikipedia.org/wiki/Abbe_Lacaille) in 1751-1752.
Called The Diamond Cluster because of its stellar (http://en.wikipedia.org/wiki/Stellar) clarity. The cluster itself is easily visible with the naked eye from dark skies but binoculars will yield a much better view. The Diamond Cluster contains two beautiful 5th magnitude red giants (http://en.wikipedia.org/wiki/Red_giants) and three double stars (http://en.wikipedia.org/wiki/Double_stars). A small telescope (http://en.wikipedia.org/wiki/Telescope) would be required to split the double stars. It contains about 100 stars that appear about the same size as a full moon (http://en.wikipedia.org/wiki/Moon).
NGC 2516 and the recently discovered nearby star cluster (http://en.wikipedia.org/wiki/Star_cluster) Mamajek 2 (http://en.wikipedia.org/w/index.php?title=Mamajek_2&action=edit&redlink=1) in Ophiuchus (http://en.wikipedia.org/wiki/Ophiuchus) have similar age and metallicity (http://en.wikipedia.org/wiki/Metallicity). Recently, kinematic evidence was presented by E. Jilinksi and coauthors that suggests that these two stellar groups may have formed in the same star-forming complex some 135 million years ago
