Observing Visual Double Stars (English and French Edition)

Tells how binary or double stars were originally discovered, and offers practical advice on how to identify them and measure their variations

"This book can be used in positional astronomy classes or as collateral reading in history of science courses. It is a 'must' for astronomy graduate students."--"Science Books & Films" "Not only does Observing Visual Double Stars urge you to join these dedicated observers, it also gives you a sense of purpose and urgency about your nightly vigils. Even now, many close binaries are passing unobserved through critical phases of their orbits-potentially priceless data lost for lack of observers."--"Astronomy" " This book can be used in positional astronomy classes or as collateral reading in history of science courses. It is a 'must' for astronomy graduate students." --"Science Books & Films" " Here's one of the most important books ever published for the dedicated stargazer - and in an important branch of observational astronomy. Translated from the 1978 French edition by Canadian astronomer Alan Batten, Observing Visual Double Stars has arrived at a time ripe for a revival of this field.... " In eight chapters, Couteau covers everything a telescope owner needs to know about double star observing. Topics range from the history of discovery and observations through the varied techniques of micrometer measurement to data reduction and orbit computation.... Especially valuable is a catalog of 744 pairs of stars suitable for small telescopes which contains the latest available position angles and separations for each object...
