Star And Planet Locator
A very handy rotating star, planet and constellation plotting map. Just turn the inner map until the time of day (or night, rather!) matches the day of the year dial—then hold it above and in front of your head with the correct direction down (i.e. south, if you're looking at things in the southern sky) and the friendly 8 1/2"x8 1/2" chart will locate or identify what you're studying. Shows the location of 500 stars, and has a 16-page instructional booklet with it. This chart is designed for 40¬∞N but is useful for any mid-latitude area of the Northern Hemisphere.
