The Cambridge Starfinder Pack contains three essential items to get you started on the fascinating hobby of astronomy -- a star chart, a moon map and a planisphere. The Star Chart is an attractive wall chart (approximately 3 feet by 4 feet in size) showing all the stars visible to the naked eve. The chart is arranged into three maps that cover the whole sky. As a bonus, it contains rainier clusters and galaxies visible with binoculars and lists constellations, double stars and variable stars. The Moon Map shows 500 craters and other features on the nearside in beautiful detail and locates landing sites of spacecraft, including Apollo. 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 the 42degree version. Those in states south of this arc require the 32degree version.
