Blue dust clouds and energetic stars inhabit this telescopic vista, less than 500 light-years away toward the northern boundary of Corona Australis, the Southern Crown. The dust clouds effectively block light from more distant background stars in the Milky Way. But the striking complex of reflection nebulas cataloged as NGC 6726, 6727, and IC 4812 produce a characteristic blue color as light from the region's bright blue stars is reflected by the cosmic dust. At the left, smaller yellowish nebula NGC 6729 bends around young variable star R Coronae Australis. Just below it, glowing arcs and loops shocked by outflows from embedded newborn stars are identified as Herbig-Haro objects. On the sky, this field of view spans about one degree, corresponding to almost nine light-years.
