NGC 6729

NGC 6729 (also known as C 68) is a reflection nebula in the constellation Corona Australis. was discovered by Johann Friedrich Julius Schmidt in 1860.La nebula is located on the line that joins the stars γ Coronae Australis and ε Coronae Australis, both of fifth magnitude; the region of sky between the two stars appears strongly obscured by interstellar dust, on which some bright nebulae stand out, such as NGC 6726 and NGC 6727. The nebula NGC 6729 is the smallest of the group in size, but it can be recognized by its markedly triangular shape that is brighter on one vertex, making it similar to a comet. Its brightness is variable, a characteristic that makes it resemble, as well as in shape, NGC 2261, the Hubble Variable Nebula. The globular cluster NGC 6723 can also be incorporated into the same field of view.

Its declination is austral, which means that it is well observable especially from the southern hemisphere, where its observation is greatly facilitated; From the northern hemisphere it is visible low on the southern horizon only from the Mediterranean latitudes or a little further north, while in the tropical belt it is well observable. The most suitable period for its observation in the evening sky is from June to October.
