The Celestron Sky Map provides a fun way to read the night sky, and is an ideal teaching guide. Just as you wouldn't set off upon a road trip without a road map, you needn't try navigating the night sky without a map either. Even if you're experienced around major constellations, these maps help locate all kinds of fascinating objects.
The front cover has a specially designed luminous planisphere that rotates to simulate the seasonal progression of celestial objects through the sky. When the planisphere is pre-exposed to light, star positions glow brightly against a dark background-mimicking actual constellations. More than a thousand stars and deep-sky objects are listed and charted. The illustrated reference section provides basic information and the visual characteristics of various types of stars, nebulae and galaxies.
To use, hold the map above your head with the arrow facing celestial north. Turn the dial to the present date and time, and the map shows you exactly what is above you. Turn the dial as the hour changes to keep up with the orbiting sky show. Please note - these maps are for use in the northern hemisphere only.
