Hector Rafael Vazquez Rispoli in Buenos Aires, Argentina, used a telescope to capture this amazing region of the southern sky. It’s near the northern boundary of Corona Australis, the Southern Crown and contains multiple objects of interest. He wrote:

After multiple failures with this object, came the day I achieved my goal. Fortunately, the weather was on my side. Low temperature. Little wind. An excellent seeing. And a really long night.

This object has a particular beauty. The mix of dark dust and brightness of the stars is the perfect combination.

NGC 6723 is the globular cluster, in the constelletion Sagittarius near the boundary with Corona Australis.

NGC 6729 is the fan-shaped nebula.

NGC 6727, 6726 and IC 4812 are reflection/ emission nebula in the constellation Corona Australis. The characteristic blue color, reflected by the cosmic dust is produced by hot stars located inside the cloud.

All was processed with Pixinsight. Aligment, register and general proccess. Final ajustment with Photoshop.

In this area very rich in stars, spreads a dark, elongated clouds of cosmic dust. The bulk of the cloud of black dust, measures about 8 light-years long.

A similar photo, taken by another photographer, was the Astronomy Picture of the Day for June 5, 2009.
