Produktbeschreibung
ASTRONOMERS' OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments.

Double and Multiple stars are among the most fascinating astronomical objects. They range from 'optical binaries' that can be easily observed with a modest telescope, to distant and complex multiple systems that challenge even professional observers.

The first part of Jim Mullaney's book provides a comprehensive review of the different classes of double and multiple systems, along with a look at the astrophysics of these objects. This is followed by a detailed guide for amateur astronomers, describing how to observe them - using a variety of different techniques - and outlining how to record the observations.

In one book, here is all you need to observe double and multiple stars, and to understand the systems you are looking at.

Rezensionen
"James Mullaney's book Double and Multiple Stars and How to Observe Them exceeds what anyone has done with this topic before--by a whole qualitative level or two. Mullaney is one of the world's most experienced observers of double stars and "deep-sky objects." His writing is always clear, accurate and enthusiastic and this book is no exception. Double and Multiple Stars, along with Mullaney's other writings on the topic, may end up almost singlehandedly winning over a new generation of observers to the joy of double-star observing." -- Fred Schaaf

"...I can recommend Double and Multiple Stars and How to Observe Them to those who delight in seeing close points of light and those who can imagine the huge variety of suns they represent." -- Leif J. Robinson, in Sky & Telescope, October 2006
