(The Southern Crown) |
||||||||
Corona Australis is a very ancient grouping of stars. In fact it was one of the first series of constellations recorded by Ptolemy. Many believe it to represent a crown of olive leaves although everyone differs over who it belongs to, some think Sagittarius and other believe it to be property of Chiron the centaur. | ||||||||

NGC 6726-7-9 and IC 4812: | |||||||
This tranquil grouping of reflection nebulae is in a way serendipitous because it wouldn't exist if not for a group of stars embedded in a giant dust cloud. This dust cloud is exceedingly active as indicated by numerous hook shaped objects that are Herbig Haro objects. NGC 6726-27 is a pair of nebulae with NGC 6729, a comet shaped aquamarine nebula to the left. IC 4812 is an irregular blue cloud that surrounds a double star. Above the complex lies the globular cluster NGC 6723, which lies thousands of light years further in the distance in Sagittarius. |

The reflection complex of NGC 6726 is at an unbelievably close distance of 500 light years. It is surrounded by many different various objects, mouseover for their names. | ||||||||
