Binoculars are easy to transport, comfortable to carry, and quick to set up: the ideal optical all-round tool! "Fern-Seher" is the first German-language book that not only explains the types and features of binoculars but also provides selection tips for various applications. Numerous illustrated examples clarify image errors, cleaning, and repair. The second part of the book offers detailed guidance for looking upward: in addition to observing the Moon and planets, it explains safe methods for solar observation. Additionally, more than two dozen rewarding targets beyond the solar system are presented - including realistic images that show the objects as they appear through binoculars. A must-have for all binocular enthusiasts, both astronomical and non-astronomical!.
