The Dark Doodad Nebula is a dark nebula located near the globular cluster NGC 4372, having a length of nearly three degrees of arc. 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). Although officially unnamed, this long molecular cloud has come to be known under this name. It can be found in the southern constellation of Musca (the Fly) with strong binoculars.
This cloud consists of regions of dense gas and dust, and is one of the closest star forming regions to the Solar System. It was described in Sky & Telescope as one of the finest dark nebulae—one that is "wonderful, winding, and very definite." Just to the east of the southern end of the Dark Doodad is the globular cluster NGC 4372.
The Dark Doodad was named by American amateur astronomer and writer Dennis di Cicco in 1986 upon seeing an image he took from Alice Springs in central Australia. Steven Coe gave it the name Sandqvist 149, because he believed it should be named after the astronomer who found it, though he acknowledges that the popular term prevails.
