Visual Astronomy in the Suburbs pdf epub mobi txt 電子書 下載 2024
Most amateur astronomers, because they live in or near cities, have to carry out their observing from relatively light-polluted sites. It is possible to reduce the effects of a poor location by the use of CCD imaging, but many observers prefer to look at astronomical objects rather than photograph them. Skill, observing techniques, and modern technology - such as image intensifiers - can now be used to astonishing effect to observe the night sky in real-time. Illustrating the book with images and some of his own superb drawings, Antony Cooke explains how to observe some of the most spectacular objects from less than perfect observing sites.
