Messier 30, also known as M30 or NGC 7099, is a globular cluster of stars in the constellation Capricornus, discovered by Charles Messier in 1764, who described it as a circular nebula without a star. Through binoculars it appears as a hazy patch of light about four arcminutes wide, while larger instruments resolve individual stars and reveal a compressed core about one arcminute across.
