Caelum (pronounced /ˈsiːləm/; earlier Cæla Sculptoris (Latin: the sculptor's chisel) is a minor southern constellation introduced by Nicolas Louis de Lacaille.

[edit] Notable features
Caelum is a faint constellation, having no star brighter than fourth magnitude. Its brightest star, and the one closest to earth at 65.7 light years, is the magnitude 4.45 α Caeli. It is also the eighth smallest constellation, with an area just less than that of Corona Australis.
Caelum has little to offer for the small telescope. A small telescope splits γ Caeli into a magnitude 4.5 red giant and a magnitude 6.34 white giant. Larger telescopes are needed to see several NGC objects, all galaxies, but none brighter than magnitude 11.5 or larger than 3 arcseconds.[1]
