NGC 6742 (also known as Abell 50) is a planetary nebula in the constellation Draco.[1] NGC 6742 was discovered by German-British astronomer William Herschel in 1788. Very few studies have been carried out on NGC 6742 and the identification of the central star of the nebula by the Kepler Space Telescope is uncertain.[2]
