Our next target is a two-for-one because it combines an open cluster and an emission nebula. Through telescopes up to 8 inches in aperture, you’ll mainly see the open cluster, NGC 6604.
NGC 6357 is known as an emission nebula, a region of space where gas is ionized by extreme ultraviolet radiation, which, in the case of NGC 6357, is caused by its massive young blue-white stars.
