Double & Multiple Stars, and How to Observe Them is written specially for practical amateur astronomers who not only want to observe, but want to know and understand the details of exactly what they are looking at. It is a mine of information for all levels of amateur observers, from the beginner to the experienced.

The concept of the book and of the series is to present an up-to-date detailed description of the objects, their physics and their evolution (part one); and then (part two) to consider how to observe and record them successfully. Increasing light pollution throughout the world does not affect the viewing of double and multiple stars. More and more amateur astronomers are therefore turning to this interesting and scientifically useful area.

It will also be bought by those who are not practical astronomers but simply want to find out more about these unusual star systems.

In two parts: (i) a comprehensive review of binary and multiple star systems, and (ii) observing and recording techniques for amateurs The very latest detailed theories and descriptions of multiple systems How to observe visual doubles, binary and multiple stars using a variety of techniques

Klappentext

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.

Zusammenfassung
