The Jewel Box Cluster,
NGC 4755, is an open
cluster in the
constellation Crux,
originally discovered by
Nicolas Louis de Lacaille
during 1751–1752. This
famous cluster was later
named the Jewel Box by
Sir John Herschel when
he described its
telescopic appearance as
"a casket of variously
coloured precious
stones." It is easily
visible to the naked eye
as a hazy star some 1.0°
southeast of the first-
magnitude star Beta
Crucis (courtesy of
Wikipedia).
