! A chapter about amateur double-star observers ! gives the human touch. With 25 chapters, each devoted to a different aspect of visual binaries, the book covers the waterfront. 125 (1185), 2005) "This book, which is aimed at amateur astronomers and the general reader, gives an account of the current state of play in the observation and measurement of visual double stars. I recommend it to anyone with an interest in binary stars who wants to learn more about these fascinating objects." (Jocelyn Tomkin, The Observatory, Vol.

(Jocelyn Tomkin, The Observatory, April 2005) "Bob Argyle, who is editor of the book ! is a keen double-star observer and an engaging feature is the way his enthusiasm for his subject animates the text. Amateur astronomers who have gone beyond 'sight-seeing' and want to make a genuine scientific contribution will find this a fascinating and rewarding field - and this book provides all the background and practical information that's needed. The book caters for the use of every level of equipment, from simple commercial telescopes to micrometers and CCD cameras.

Bob Argyle, a professional astronomer at Cambridge University, shows where enthusiastic amateur observers can best direct their efforts. This is where amateur astronomers can help.
Orbiting satellites, ground-based observatories and interferometers have all helped discover many hundreds of new pairs - but this has left enormous numbers of wide, faint pairs under-observed or not observed at all. Double stars are the rule, rather than the exception: our solar system, having a single sun, is in the minority.
