Since comet Shoemaker-Levy collided with the planet Jupiter with stupendous force in 1994 there has been an upsurge of amateur interest in comets. Most comets are first discovered by amateur astronomers because there are so many amateurs looking for them, and techniques and instruments have improved dramatically in the past few years. After a short but detailed introduction to the comets themselves Nick James and Gerald North describe comet hunting, photographing and imaging comets, and digital image processing. The use of computers for orbital calculations and even helping to discover new comets is given a full chapter, as are advanced techniques including comet photometry and spectroscopy. This comprehensive book has an accompanying CD-ROM and is at once a "primer" for comet hunters and a reference text for more advanced amateur astronomers.
A guide to astronomy which attempts to offer the most up-to-date
information on the subject. Designed to be used for either
individual study or classroom use, the book covers the GCSE
syllabus requirements and relevant elements of physics, general
science and general studies courses.
Every year large numbers of people take up the study of astronomy,
mostly at amateur level. There are plenty of elementary books on
the market, full of colourful photographs, but lacking in proper
explanations of how and why things are as they are. Many people
eventually wish to go beyond the 'coffee-table book' stage and
study this fascinating subject in greater depth. This book is
written for them. In addition, many people sit for public
examinations in this subject each year and this book is also
intended to be of use to them. All the topics from the GCSE
syllabus are covered here, with sample questions at the end of each
chapter. Astronomy Explained provides a comprehensive treatment of
the subject in more depth than is usually found in elementary
works, and will be of interest to both amateur astronomers and
students of astronomy.
Gerald North's complete practical guide and resource package
instructs amateur astronomers in observing and monitoring variable
stars and other objects of variable brightness. Descriptions of the
objects are accompanied by explanations of the background
astrophysics, providing readers with real insight into what they
are observing at the telescope. The main instrumental requirements
for observing and estimating the brightness of objects by visual
means and by CCD photometry are detailed, and there is advice on
the selection of equipment. The book contains a CD-ROM packed with
resources, including hundreds of light-curves and over 600
printable finder charts. Containing extensive practical advice,
this comprehensive guide is an invaluable resource for amateur
astronomers of all levels, from novices to more advanced observers.
Gerald North is a lifelong amateur astronomer. In addition to being
a member of the British Astronomical Association since 1977, he is
also the author of many books, including Advanced Amateur Astronomy
(Cambridge, 1997) and Observing the Moon (Cambridge, 2000).
Written by an accomplished amateur astronomer and available for the first time in North America, this advanced guide is designed to take your evening explorations to new heights. Beginning with an explanation of the fundamental principles of practical astronomy, author North provides essential information on telescope optics, the atmosphere, astrophotography, electronic imaging, and telescope hardware (including how to select equipment and diagnose faulty telescopes). This knowledge is then applied to the full range of celestial bodies accessible by telescope: the solar system, stars and galaxies. For those amateur astronomers who are bored with making simple observations, chapters on photometry, spectroscopy and radio astronomy bring observational astronomy to a level where data of real scientific value can be acquired. This book is a must for any amateur astronomer wanting a new way to look at the sky.
Written by an experienced and well-known lunar observer, this is a
hands-on primer for the aspiring observer of the Moon. Whether you
are a novice or are already experienced in practical astronomy you
will find plenty in this book to help you raise your game to the
next level and beyond. In this thoroughly updated Second Edition,
the author provides extensive practical advice and sophisticated
background knowledge of the Moon and of lunar observation. It
incorporates the latest developments in lunar imaging techniques,
including digital photography, CCD imaging, and webcam observing,
and essential advice on collimating all common types of telescope.
Learn what scientists have discovered about our Moon, and what
mysteries remain still to be solved. Find out how you can take part
in the efforts to solve these mysteries, as well as enjoying the
Moon's spectacular magnificence for yourself!
