Manufacturer's Description Celestron Sky Maps are the ideal teaching guide for learning the night sky. You wouldn’t set off on a road trip without a road map, and you don’t need to try to navigate the night sky without a map either. Even if you already know your way around the major constellations, these maps can help you 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. The maps measure 35 cms x 29 cms and are printed on a heavyweight, moisture resistant card stock. The pages have a special comb binding so they can lay flat or be folded over Product Description Learn the night skies of the Northern Hemisphere with Celestron Sky Maps! This classic collection of seasonal star charts, topped off by a glow-in-the-dark luminous star finder, or planisphere, has been around for years and years! It continues to be so popular because beginning stargazers as well as seasoned amateur astronomers find that this book provides most everything they need to find constellations quickly and delve into seasonal night sky treasures with ease. The front cover of this publication will be used well and often! It is a planisphere—a rotatable star wheel that can be aligned with any date and time (past, present & future), resulting in a display of the night sky for that period of time. When the star finder is pre-exposed to light, all of the major stars will glow in the dark, mimicking the way they actually look in the night sky. Inside you will find a collection of more detailed star charts for each of the four seasons. Directions 1. Align the planisphere with the desired date and time to see the night sky for that period. 2. Use the star charts inside to find objects in the sky with binoculars or a telescope by 'star-hopping'.
