Discover the Moon pdf epub mobi txt 電子書 下載 2024
The Moon is accessible to everyone, and easy to observe even in big cities. It is a prime target for aspiring astronomers and for those who are merely curious about the night sky. This easy-to-use guide to discovering lunar sites takes the reader through fourteen observing sessions from New Moon to Full Moon. For each evening, the book shows which craters, mountains and other features can be seen, and how to find them. Each photograph shows what the observer actually sees through a telescope, solving the usual difficulties of orientation confronting beginners. Images are shown as they appear through both refracting and reflecting telescopes. Maps printed on the front and back flaps of the book show the whole Moon with sites as seen through a refractor, through a Newtonian reflector, or, when turned upside-down, through binoculars.
