The Jewel Box Cluster, also known as the Kappa Crucis Cluster, is an open star cluster located in the southern constellation Crux.
The cluster has an apparent magnitude of 4.2 and lies at an approximate distance of 6,440 light years from Earth. It has the designation NGC 4755 in the New General Catalogue. The Jewel Box Cluster can easily be seen without binoculars and appears as a fuzzy star to the naked eye.
It is one of the finest objects in the southern sky, covering an area of 10 arc minutes, and best seen in binoculars and telescopes. Large binoculars and small telescopes easily resolve the pyramid shape formed by the cluster’s brightest stars.

The Hyades are a star cluster located in Taurus constellation and the nearest open cluster of stars to the solar system. Also catalogued as Collinder 50 or Melotte 25, the cluster has an apparent magnitude of 0.5 and lies at a distance of 153 light years, or 47 parsecs, from Earth.
The brightest stars in the Hyades cluster form a V shape that marks the head of the celestial bull. The cluster lies along the same line of sight as Aldebaran, the brightest star in Taurus, but the bright giant is not a member of the cluster and lies much closer to Earth.

The nebula’s name means “divided into three lobes,” and refers to the object consisting of three types of nebulae and an open star cluster. The open cluster is surrounded by an emission nebula, a reflection nebula, and a dark nebula within the emission nebula that gives M20 the trifurcated appearance for which it is known.
The dark nebula was catalogued by Edward Barnard and has the designation Barnard 85 (B85). The Trifid Nebula has the designation NGC 6514 in the New General Catalogue.
