Jewel Box Cluster - NGC 4755

The Jewel Box (also known as the Kappa Crucis Cluster, NGC 4755, or Caldwell 94) is an open cluster in the constellation Crux. This cluster was named the "Jewel Box" by John Herschel when he described its telescopic appearance as "...a superb piece of fancy jewellery". It is easily visible to the naked eye as a hazy star about 1.0° southeast of the first-magnitude star Mimosa (Beta Crucis), given the designation "Kappa Crucis".
It is only seen in the Southern Hemisphere from March to August.
