The Corona Australis Complex is a very interesting area in the Southern Crown and Sagittarius areas in the heart of the Milky Way. The top blue reflection nebula is NGC 6723-7 and the bottom blue is IC 4812. The dark nebula is desiginated HMSTG 1099, the 1099th object in the catalogue of dark interstellar dust clouds by astronomers Hartley, Manchester, Smith, Tritton and Goss. NGC 6723 is a globular star cluster at top right and is located about 29,000 light-years away from Earth and spans about 65 light-years in size. Globular star clusters contain hundreds of thousands to millions of stars and orbit around the Galaxy in a spherical halo surrounding it. These are some of the oldest stars in the Universe, over 10 billion years old.
