   Explanation: The Dark Doodad Nebula drifts through southern skies, a
   tantalizing target for binoculars toward the small constellation Musca,
   The Fly. A dusty interstellar cloud, it's seen against rich starfields
   just south of the Coalsack Nebula and the Southern Cross. Stretching
   for about 3 degrees across this telescopic field of view, the Dark
   Doodad is punctuated near its southern tip (upper right) by yellowish
   globular star cluster NGC 4372. Of course NGC 4372 roams the halo of
   our Milky Way galaxy, a background object some 20,000 light-years away
   and only by chance along our line-of-sight to the Dark Doodad. About
   700 light-years distant and over 30 light-years long, the Dark Doodad's
   well defined silhouette belongs to the potentially star-forming Musca
   molecular cloud. The dusty Dark Doodad's delightfully alliterative
   moniker was first coined by astro-imager and writer Dennis di Cicco in
   1986 while observing Comet Halley from the Australian outback.
