This practical, hands-on guide is the sailors essential atlas of the sky. Assuming no prior knowledge, this comprehensive, practical handbook helps the user at sea or on land read and understand the changing sky. Readers are given hands-on advice on how to read the night sky and star charts, as well as information on whether particular stars can be seen with the naked eye or require binoculars or a telescope. At the core of the book are 150 sky charts, showing what features can be seen in each position and when. Every constellation in the northern and southern hemisphere is mapped out. Simple methods are given for finding the biggest, brightest stars and then identifying other lesser stars by their relative position. For sailors out of the sight of land, celestial navigation really comes into its own - providing a sure means of checking the boats position even when GPS and other electronics malfunction. This book will provide a complete reference as to what stars and constellations they should be able to use when and where in the world. The Practical Skywatchers Handbook is ideal for anyone, on land or sea, wanting a complete guide to the night sky.
