What is a Sky Map and WHY do I Need One?

A sky map is a star gazer's best friend. Once you learn how to use this simple object you will notice that your night sky takes on meaning. And that is what a map does, right? Gives meaning to complicated systems, whether they be roads or stars.

A sky map needs to be current for the month you are presently in, that way when you look up the stars above will be in about the same place as the map.

How to Use a Sky Map

A Sky map shows the stars, planets, and other interesting things in the sky as they are for that specific month. Begin by figuring out your compass directions. Your sky map will have the compass directions printed on it. You will want to turn your map until you are facing the same direction as the direction on the map directly in front of you.

Many astronomy newbies like to find the North Star (Polaris) because it is bright and easy to spot. In this case you would go outside when it is dark, face North, then turn your map around until the N (for north) is directly in front of you.

Your map is a big circle - the center if the circle is right over your head. The outside edge of the circle is the horizon. By looking at the map you can tell how far overhead Polaris should be and you can direct your gaze to that area of the sky.

It is quite easy to find! You just have to try!
