Practical Astronomy Handbook Series #0003: Observing the Sunby Peter Taylor
Synopses & Reviews
Observing the sun is one of the most interesting and rewarding facets of astronomy to which amateurs can contribute meaningful data. It is the one branch of astronomy that requires only modest equipment and that can be pursued during the day. Peter Taylor, long-time chairman of the Solar Division of the American Association of Variable Star Observers, is a keen and highly experienced observer of the Sun. In this book he explains in a clear and practical way everything that a telescope user needs to know in order to make solar observations. The book deals with such topics as the historical background of solar observing, choice of equipment for the safe conduct of solar observations, observations of sunspots, and reporting observations. New techniques, such as electronic recording and the operations of radio telescopes, are also included. The level of presentation is understandable to anyone with basic astronomical knowledge and some experience in handling a small telescope.
A clear and practical account of everything that a telescope user needs to know in order to make solar observations.
Includes bibliographical references (p. 153-156) and index.
