NGC 6530 is a cluster with nebula in Sagittarius
NGC 6530 (MWSC 2798) is a cluster with nebula in the constellation Sagittarius . It shines at magnitude 4.6 and spans 6′. It is an easy target in binoculars, and it is highest in the evening sky in August.
Nebula: a cloud of gas and dust. Emission nebulae glow on their own, lit by ultraviolet light from hot young stars; reflection nebulae shine by starlight scattered from dust; dark nebulae block the light behind them.
