Where can you find the best maps of the night sky?

There are several websites that provide accurate star maps, including AstroViewer.com. The most important thing to keep in mind when choosing a star map is that your location makes a significant difference.

There is little use in a star map for the sky above New York City when you live in Los Angeles as the view will be from a very different perspective. Therefore, it is important to use your geographical coordinates in conjunction with a star map for the most accurate picture. A good way to circumvent this complexity is to use an app on your phone, like Google Sky, since most phones have GPS functionality and can accordingly populate the relevant chart.
