NGC 4372

NGC 4372 (aka Caldwell 108) is a globular cluster in the southern constellation of Musca (central left side). It is southwest of γ Muscae (Gamma Muscae the bright blue star) and west of the southern end of the Dark Doodad Nebula (Sandqvist 149), a 3° thin streak of black dust across a southern section of the great plane of the Milky Way.

The cluster has highly peculiar chemistry similar to NGC 5694, being extremely iron-poor yet having super-solar abundances of magnesium and titanium.
