Double & Multiple Stars, and How to Observe Them (Astronomers' Observing Guides) - Softcover

Über die Autorin bzw. den Autor

James Mullaney is an astronomy writer, speaker and consultant who has published nearly a thousand articles and nine books on observing the wonders of the heavens, and logged over 20,000 hours of stargazing time with the unaided eye, binoculars and telescopes.  Formerly Curator of the Buhl Planetarium & Institute of Popular Science in Pittsburgh and more recently Director of the DuPont Planetarium at USCA, he served as staff astronomer at the University of Pittsburgh's Allegheny Observatory and as an assistant editor for Sky & Telescope magazine.  One of the contributors to Carl Sagan's award-winning Cosmos PBS-Television series, his work has received endorsement from such notables (and fellow stargazers) over the years as Sir Arthur Clarke, Johnny Carson, Ray Bradbury, Dr. Wernher von Braun, and former student - NASA scientist/astronaut Dr. Jay Apt.  His lifelong mission has been to "Celebrate the Universe!" - to get others to look up at the majesty of the night sky and personally experience the joys of stargazing.  In recognition of his work, he has been elected a Fellow of the prestigious Royal Astronomical Society of London.

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.
