Outlining all the constellations visible anywhere in the Northern Hemisphere, this guide includes 12 maps showing the entire sky as it appears during each month of the year, plus 23 star charts that depict smaller regions of the sky in great detail. Exploring the mythology behind the constellations, Richard Berry also discusses the movements of the stars, how to find your way around the moon and the planets, making an astronomer's flashlight, and using a telescope.
