This bright cluster itself is easily visible with the naked eye from dark skies but binoculars will yield a much better view. It contains two beautiful 5th magnitude red giants and three double stars. A small telescope would be required to split the double stars, which are all pairs of 8-9 magnitude and 5-10" separation.
NGC 2516 and the recently discovered nearby star cluster Mamajek 2 in Ophiuchus have similar age and 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.
