NGC 4372 (also known as Caldwell 108) is a globular cluster in the southern constellation of Musca. It is southwest of γ Muscae (Gamma Muscae) and west of the southern end of the Dark Doodad Nebula (Sandqvist 149), a 3° thin streak of black across a southern section of the great plane of the Milky Way.
NGC 4372 "is partially obscured by dust lanes, but still appears as a large object some 10 arcseconds in diameter," according to Astronomy of the Milky Way (2004).[1]
The cluster has highly peculiar chemistry similar to NGC 5694, being extremely iron-poor yet having super-solar abundances of magnesium and titanium.
