Melotte 15 (also known as Collinder 26) is an open cluster embedded within IC1805 (The Heart Nebula). And it's interesting to note that the radiation from this cluster of stars is the primary source of the ionization of the Hydrogen gas in the nebula, as well as the primary driver of the shape of the nebula itself by way of its solar winds.
Melotte 15 is located 7500 ly away from earth and appears in the the constellation Cassiopeia.
