Musca, The Fly, is so small you can see all the relevant stars in the same field of vision. To find the constellation drop due south one full FOV from alpha Crucis (the Southern Cross).
Alpha Muscae is the brightest star in this small constellation. It's found by dropping one binocular field due south from alpha Crucis. If you have a small telescope, beta Muscae (in the same field) is an interesting binary. This is a close binary with an orbit of 383 years. Presently (J2000) the companion is 1.3" away at a PA of 43º. Also worthy of investigation is the globular cluster NGC 4833, quite bright and compact and just visible in binoculars. It's north-northwest of delta Muscae, in the same FOV. A portion of the dark nebula known as the Coal Sack spills over into Musca, but most of it is found in Crux to the north.
