Beschreibung:
This handbook is a guide to exploring the night sky and its wonderful telescopic sights. All eighty-eight officially recognized constellations in both hemispheres are presented in natural groups, related by their origin and location. The author, a former astronomy instructor and planetarium director, has for over thirty-five years, researched myths from all over the world to identify the most memorable stories which link multiple constellations in a single story. Thus, the interested observer may discover that it will be easier to use already known constellations to locate and remember new constellations. The author has found that showing each constellation figure with a simple line drawing is helpful for remembering each constellation. He includes photographs of many of the brighter celestial objects, as well as many accompanying drawings which illustrate how the telescopic views differ from the photographs.
This handbook is a guide to exploring the classical night sky and its wonderful telescopic sights. All 88 officially recognized constellations are presented in natural groups which are related by their origin and location in the sky. Each group is explained by a fascinating story which tells what each constellation represents, how it appears in the sky, and why the other constellations of the group are close by, or related in some other manner. Some of these stories are classical myths which show how and why ancient cultures saw the constellations as related groups. Others are about more modern astronomers who sought recognition by filling in the gaps between the ancient constellations with inventions of their own. Both types of stories are crafted to make the constellation groups memorable, so that amateur astronomers can not only locate and recognize the constellations more easily, but also be able to pinpoint the celestial objects they contain more quickly.Specific instructions are given for finding each constellation, how to spell and pronounce the constellation and star names, plus the origins of the star names. Finder charts show each constellation group and a large area of sky around the group. These charts also indicate pointer stars which aid in finding the constellations.More detailed charts show how each constellation figure is visualized through simple line drawings. For each constellation, there is a table of about 10 to 30 telescopic objects selected to include a wide range of difficulty. Some can be glimpsed with the unaided eye, others require a 12 or 14 inch telescope. All the most prominent telescopic objects are included, plus a varied selection of interesting, but much more difficult objects. The tables include each object's celestial coordinates, type, size, brightness, other information specific to each type of object, and a recommendation of the appropriate telescope size needed for good viewing.There are also photographs of constellations and telescopic objects, detailed locator charts for the hard-to-find objects, and plots of binary star orbital motions. The same charts used to show the constellation figures are repeated, with the addition of symbols indicating the locations of all the selected telescopic objects.An index and seven appendices help the user find specific objects or classes of objects.
