دانلود کتاب Binocular Highlights: 99 Celestial Sights for Binocular Users

Binocular Highlights is a tour of 99 different celestial sights - from softly glowing clouds of gas and dust to unusual stars, clumps of stars, and vast star cities (galaxies) - all visible in binoculars. Each object is plotted on a detailed, easy-to-use star map, and most of these sights can be found even in a light-polluted sky. Also included are four seasonal all-sky charts that help locate each highlight. You don't need fancy or expensive equipment to enjoy the wonders of the night sky. In fact, as even experienced stargazers know, to go beyond the naked-eye sky and delve deep into the universe, all you need are binoculars - even the ones hanging unused in your closet. If you don't own any, Binocular Highlights explains what to look for when choosing binoculars for stargazing and provides observing tips for users of these portable and versatile mini-telescopes.
