Corona Australis dust nebula

This beautiful complex of various objects is located in a southern constellation of Corona Australis, with a bright Milky Way as background.

Huge dark cloud of gas and dust spans some 8 light years across. A few bright stars are embedded in the dark nebulosity. Fine cosmic dust preferentially reflects shorter wavelengths, therefore these stars are surrounded by blue reflection nebulosity - NGC 6726, 6727, 6729 and IC 4812. The reflection and dark nebulosity complex is located some 500 light years from Earth.

Variable star R Coronae Australis is surrounded by somehow yellowish nebulosity.

Far in a background, probably as distant as 30.000 light years, lays globular cluster NGC6723. Actually, it is located just across the border in Sagittarius.
