Description:
A fleeting glimpse into the Southern Sky. Corona Australis (Bottom left) is a faint constellation just beneath Sagittarius and is home to the Corona Australis Molecular Cloud, a star-forming region 430 light-years away from our Solar System, adjacent to the nebulosity is the globular cluster NGC 6723, though close in the sky, NGC 6723 is actually ~28,000 light years further away. Imaging was quite a challenge as Corona Australis was only 14 degrees above the horizon at the time of imaging and the afternoon's storms were still clearing out. Thankfully enough subs were cloud-free to provide a decent SNR.
