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.
