The globular cluster NGC 4372 in the constellation Musca is obscured by interstellar gas and dust and therefore appearing in a yellow-red shade.
It is situated south of the dark Doodad Nebula, a nice extended bow of obscuring dust.
Scientific investigations showed, it is a cluster with one of the lowest metallicities.
