Maps and text show stars, planets and other objects in the sky night, all visible with binoculars or a small telescope. Photo-realistic images opposite maps show how the same portion of sky looks to the naked eye, allowing less experienced observers to quickly find specific sky objects of interest. The maps can be used for planning observations, navigating from one part of the sky to another, and for quick reference. The guide can be used anywhere in the world and at any time of the year. The maps include observing targets, seasonal maps, and magnitude 5.5 star maps. Additional features are a plastic-laminated lay-flat binding for outdoor use, flaps to use as page markers, constellation maps, relief Moon maps, and a quick-access page-referenced constellation listing on the back flap. --From publisher description.
