Observing and Measuring Visual Double Stars (second edition)

Available Amazon, Barnes & Noble, & everywhere--be sure to
look for the 2nd edition, blue cover. Or choose eBook

There are more binary stars visible in the night sky than there
are single stars, and there are enormous numbers of wide, faint
pairs under-observed or not observed at all - professional
astronomers just don't have the available time to study them.
This is where amateur astronomers can help. Bob Argyle, a
professional astronomer at Cambridge University, shows where
enthusiastic amateur observers can best direct their efforts.
The book caters for the use of every level of equipment, from
simple commercial telescopes to micrometers and CCD cameras.
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. Includes a
free CDROM represents an informative snapshot of continually
evolving catalogues, including; the United States Naval
Observatory catalogues, the WDS, the Second Delta-m catalogue,
the Fourth Interferometric catalogue and the Sixth orbital
catalogue to be used in conjunction with the USNO website.
The second edition of Observing and Measuring Visual
Double Stars contains a significant amount of completely new
material inspired by the work done by observers … since the
first edition was published. Fifteen skilled and experienced
astronomers have contributed chapters on their own
specialization in the various fields. These include how to use
the Internet to carry out precise astronomical measurement, an
excellent guide to sketching double stars, and information on
how to image double stars of unequal brightness. This new
edition is the definitive book for those who are serous about
this fascinating aspect of astronomy! (From the back cover of
the book.)

The Double Star Reader: Selected Papers from the Journal of
Double Star Observations
Editors: R. Kent Clark, Russell M. Genet,
Available for advance order from
www.CollinsFoundationPress.org for $29.95 (plus shipping and
handling)

The majority of stars are gravitationally bound systems of two
or more stars that are only distinguishable through a telescope.
Their orbital periods range from days to millennia, often making
double star research a multi-generational endeavor. Thus,
astronomers today contribute measurements of systems that have
been observed, in many cases, for centuries. Since the
fundamentals of double star research are straight-forward and
entry equipment is low cost, double star research is open to
amateur and student astronomers. This book exposes the reader to
a diverse sampling from the Journal of Double Star
Observations detailing both historical and modern
observations as well as the techniques and technologies used by
amateurs, students, and professionals.
