SKY MAP (STAR CHART): SEPTEMBER 2016

[elleng]

When you face westward at this time of year, the night sky is dominated by three bright stars: Altair, Vega, and Deneb. These three form the Summer Triangle, as illustrated in purple on this month’s sky map.

Look nearly straight up to find the bright star Deneb, which sits at the top of the Northern Cross asterism (unofficial star pattern), itself a part of the large constellation Cygnus, the Swan. The Northern Cross is one of those asterisms that, once seen, is easily recognized in the future.
