The Cambridge Starfinder Pack contains three essential items to get you started on the fascinating hobby of astronomy. The Star Chart is an attractive wall chart (approximately 3 feet by 4 feet) showing all the stars visible to the naked eye. The chart is arranged into three maps to cover the whole sky. Fainter clusters and galaxies visible in binoculars are included. Constellations, double stars and variable stars are listed. The Moon Map shows 500 craters and other features on the nearside in beautiful detail. Landing sites of spacecraft, including Apollo, are shown. Finally, the Planisphere is a traditional and practical star finder for locating stars and constellations at any hour of the year. Observers in Canada and states located north of an arc through San Francisco, St Louis and Washington will need this 42° version. Those in states south of this arc require the 32° version (ISBN 0521 669545).
