When using a star chart, hold the chart up in front of you, and rotate it so that the direction you are facing is on the bottom of the chart. Then, hold the chart up in front of you, and compare the stars in the sky to the stars on the map.

Star charts represent constellations and stars when viewed from a specific latitude, so depending on how above or below that latitude you are standing, the stars shift accordingly.
