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).

Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.

This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.

This is the ultimate, easy-to-read guide for "eclipse-chasers" which includes everything an eclipse chaser needs. There are some important eclipses coming up in the years ahead and the technology available to amateur astronomers is improving fast. The book provides "eclipse virgins" with a good feeling for what a trip abroad to an eclipse is like – including a humorous look at all the things that can and have gone wrong. Travel details are included, essential in these days of high-security. And of course the first part of the book contains a wealth of information about solar eclipses and what can be observed only during a total eclipse.

Many books cover permanent astronomical objects, but few consider transient, out-of-the-ordinary astronomical phenomena. This book covers a wide range of topics, from the partly-predictable to the totally unpredictable. At one end: of the scale, it gives advice on the best ways to observe meteors, and at the other end:, it describes the best methods for undertaking painstaking searches for new comets and supernovae. The book also includes material about phenomena that occur in the lower atmosphere, such as "ozone eaters", nacreous clouds, and solar and lunar halos.

Extragalactic Novae: A historical perspective takes the reader on a journey chronicling the study of a class of eruptive variable stars known as "Novae Stella", Latin for "New Stars". These mysterious transient objects, now referred to simply as novae, have been recognized since antiquity, suddenly appearing in the night sky before slowly fading back into obscurity. The book begins with a brief introduction to the early observations, including an overview of the role that novae played in the birth of extragalactic astronomy, and concludes with a discussion of how nova observations over the past century have contributed to our knowledge of close binary star populations in nearby galaxies. Along the way, the history of our understanding of the nova phenomena, in the Milky Way and beyond, is unveiled. In particular, the author describes how the enigmatic nova eruptions were finally realized to be the result of thermonuclear runaways on the surfaces of accreting white dwarf stars, how a controversial correlation between a nova's peak luminosity and its rate of decline (the MMRD relation) has been used in extragalactic distance determinations, and how recent observations have bolstered the case that novae may form a significant channel for the production of Type Ia supernovae. These topics, and more, are recounted by an observer who has spent the past 35 years studying these fascinating objects.

Serious amateur astronomers often wonder how to find new minor planets, comets and novae and would like to know how to use photoelectric detectors to derive the temperatures of stars. These issues along with predicting future eclipses and the occultations of stars by minor planets are topics covered in this authoritative and wide-ranging guide. For each topic, sound practical methods of observation and the scientific background are given to facilitate better observations. Guidelines also show how to record and catalog observations using the recognized professional terminology and classification schemes. From the simplest pencil drawings of the moon to observations of the most distant galaxies with state-of-the-art CCD cameras and photoelectric photometers, this guide is packed with practical tips for all types of amateur observations. Volume 2 covers aurorae, meteors, double and multiple stars, variable stars, deep sky objects, novae, and supernovae.

This revised 1985 edition tells the story of supernovae, capturing the flavour of ancient astronomy.

This unique atlas contains 248 charts of more than 300 of the brightest galaxies, each specially prepared to facilitate the discovery of supernovae. The comparison of these charts with the field seen in a telescope enables any extragalactic supernova to be spotted immediately. The charts include 345 galaxies printed on translucent paper for use on a light-box, each one carrying an explanation of the constellation in which the galaxy lies, special characteristics of the galaxy, observing instructions, expected maximum brightness for the supernovae in each galaxy, and the reference for the sequence. A handbook accompanies the charts advising on their use, on how to make and record supernova discoveries, and reviewing the present understanding of supernovae. Published for an international market, these charts carry real potential for numerous discoveries of supernovae. Supernova Search Charts are is a must for both serious observers and the growing number of deep sky enthusiasts around the world.

This book is intended for amateur astronomers who are readers of Sky & Telescope magazine or similar astronomy periodicals – or are at least at the same level of knowledge and enthusiasm. Supernovae represent the most violent stellar explosions in the universe. This is a unique guide to supernova facts, and it is also an observing/discovery guide, all in one package. Supernovae are often discovered by amateur astronomers, and the book describes the best strategies for discovering and observing them. Moreover, it contains detailed information about the probable physics of supernovae, a subject which even today is imperfectly understood.
