During the holidays many people will be away from the city lights. This is a perfect time to observe our wonderful southern sky. The Moon is a waxing crescent so this is still an excellent time to look at the wonderful clusters and nebula of our southern skies with the unaided eye or binoculars.

The Milky way stretches from the Southern cross in the south to the distinctive constellation of Orion and beyond. The Milky ways' satellite dwarf galaxies, the Magellanic clouds, (between and below the bright stars Canopus and Achernar) are easily seen away from the city lights. This is the last week to get a good look at these wonders before the Moons light washes them out.
