The Southern Crown. Corona Australis is a small compact constellation nestled between Sagittarius and Scorpius, just east of Scorpion's stinger. The crown is quite old, and is said to represent the crown worn by the centaur Sagittarius (and sometimes known as "Corona Sagittarii"). Like a number of other constellations in the southern hemisphere, its Bayer stars are far from complete, and are rather faint as well.
