Corona Australis Molecular Cloud, NGC 6726, 6727, 6729, IC 4812, Globular Cluster NGC 6723 (2018)


The Corona Australis Molecular Cloud produces new stars, hot and blue, that light up the dust like two eyes of a ghostly alien.  Each eye of this alien is two stars (not double stars, but aligned from our line of sight), yet each of the four is also a close double or multiple star.  Just below the left eye is fan-shaped nebula NGC 6729.  At the fan's point is R CoA and following up closely is T CoA, both very young stars. Just to the right is curly HH100, an Herbig-Haro object spewed from a newly forming star. Appearing above the nebulosity is NGC 6723, a background globular cluster some 30,000 light years away. This is from data obtained by Martin Pugh with a Tak FSQ106.
