Nebula NGC 6729 in Corona Australis Molecular Cloud

NGC 6729, also known as Caldwell 68, is a reflection/emission nebula of the Corona Australis Molecular Cloud in the constellation Corona Australis. It was discovered by Johann Friedrich Julius Schmidt in 1861. This fan-shaped nebula opens from the star R Coronae Australis toward the star T CrA to the south-east. R CrA is a pre-main-sequence star in the Corona Australis molecular complex, one of the closer star-forming regions of our galaxy at a distance of 424 light years. NGC 6729 is a variable nebula. It shows irregular variations in brightness and in shape.
