David Levy has held a lifelong passion for comets, and is one of the most successful comet discoverers in history. In this book he describes the observing techniques that have been developed over the years--from visual observations and searching, to photography, through to electronic charge-coupled devices (CCDs). He combines the history of comet hunting with the latest techniques, showing how our understanding of comets has evolved over time. This practical handbook is suitable for amateur astronomers, from those who are casually interested in comets and how to observe them, to those who want to begin and expand an observing program of their own. Drawing widely from his own extensive experience, Levy describes how enthusiastic amateurs can observe comets and try to make new discoveries themselves. David H. Levy is one of the word's foremost amateur astronomers. He has discovered seventeen comets, seven using a telescope in his own backyard, and had a minor planet, Asteroid 3673 Levy named in his honor. He is best known as the co-discoverer of the famous 1994 Shoemaker-Levy 9 comet. Levy is frequently interviewed in the media and succeeded Carl Sagan as science columnist for Parade magazine. He has written and contributed to a number of books, most recently David Levy's Guide to the Night Sky (Cambridge, 2001).

Download David Levy's Guide to Observing Meteor Showers Book in PDF, ePub and Kindle
Meteors occur when a meteoroid, a speck of dust in space, enters the Earth's atmosphere. The heat generated when this happens causes the surrounding air to glow, resulting in 'shooting stars'. During the most spectacular meteor storms larger particles give rise to fireballs and firework-like displays! Meteors are a delightful observing field - they do not require a telescope, and they can be seen on any clear night of the year, even in bright twilight. It was the sight of a single meteor that inspired David Levy to go into astronomy, and in this book he encourages readers to go outside and witness these wonderful events for themselves. This book is a step-by-step guide to observing meteors and meteor showers. Any necessary science is explained simply and in clearly understandable terms. This is a perfect introduction to observing meteors, and is ideal for both seasoned and budding astronomers.

Download Visually Observing Comets Book in PDF, ePub and Kindle
In these days of computers and CCD cameras, visual comet observers can still contribute scientifically useful data with the help of this handy reference for use in the field. Comets are one of the principal areas for productive pro-amateur collaboration in astronomy, but finding comets requires a different approach than the observing of more predictable targets. Principally directed toward amateur astronomers who prefer visual observing or who are interested in discovering a new comet or visually monitoring the behavior of known comets, it includes all the advice needed to thrive as a comet observer. After presenting a brief overview of the nature of comets and how we came to the modern understanding of comets, this book details the various types of observations that can usefully be carried out at the eyepiece of a telescope. Subjects range from how to search for new comets to visually estimating the brightness of comets and the length and orientation of tails, in addition to what to look for in comet heads and tails. Details are also given of 20 periodic comets, predicted to return between the years 2017 and 2027, that are expected to become suitable targets for visual observing, in addition to information on a famous comet potentially visible each year and subject to great outbursts of brightness.

Download Observing Variable Stars Book in PDF, ePub and Kindle
David Levy's entertaining, well-researched book is aimed at the amateur enthusiast who likes to learn enjoyably. Beginning with advice on binoculars and telescopes, and how to observe the night sky effectively, the author goes on to describe thoroughly the field of variable star observation, a field in which amateurs have made important contributions. He shows how to interpret variations in light output in terms of the life of a star, from birth through to sometimes violent death. All of the major variable stars are described and classified, as well as other variable objects such as active galaxies, asteroids, comets and the sun. The book also contains a guide to the seasonal night sky. Throughout, practical observations serve to complement the text, producing an exciting, very readable introduction to this fascinating subject.

Download Observing Comets, Asteroids, Meteors, and the Zodiacal Light Book in PDF, ePub and Kindle
When can you see fireballs and who should you contact if you spot one? When is it best to hunt for comets and meteors and whereabouts? How do you gauge the size of the coma in the head of a comet and estimate its degree of condensation? Clear and easy to use, this guide shows you how to make successful and valuable observations and records of comets, asteroids, meteors and the zodiacal light. For each topic the historical background and current scientific understanding support a wealth of observational techniques. Comet observers are shown techniques for search and discovery. They can learn how to make visual estimates of brightness and size, and how to make photographic studies of cometary heads and tails. Asteroid hunters will find a 'life list' of quarry and guidelines on how to search for these objects and then how to photograph or electronically image them. Fruitful photographic and electronic methods for studying meteors and meteor showers are provided. Visual and photographic techniques show you how to examine the often elusive zodiacal light. The more adventurous are provided with advanced techniques on how to make successful astrometric, spectroscopic and electronic observations. This is rounded off with an invaluable list of centres world-wide to contact with your details of unusual sightings.

Download Asteroids and Dwarf Planets and How to Observe Them Book in PDF, ePub and Kindle
Dwarf planets (which were formerly called asteroids except for the planet Pluto), and the smaller Solar System bodies still called asteroids today, are making front page news, particularly those that are newly discovered and those that might present a hazard to life on Earth by impacting our planet. In this age of giant telescopes and space probes, these small Solar System bodies have advanced from being tiny points of light to bodies worthy of widespread study. This book describes the dwarf planets and asteroids themselves, their origins, orbits, and composition, and at how amateur astronomers can play a part in their detection, tracking, and imaging. The book is divided into two parts. Part I describes physical properties (including taxonomic types) of dwarf planets and asteroids, how they formed in the early life of the Solar System, and how they evolved to their present positions, groups, and families. It also covers the properties used to define these small Solar System bodies: magnitude, rotation rates (described by their light-curves), and orbital characteristics. Part II opens with a description of the hardware and software an amateur or practical astronomer needs to observe and also to image asteroids. Then numerous observing techniques are covered in depth. Finally, there are lists of relevant amateur and professional organizations and how to submit your own observations to them.

Join David J. Eicher in this fast-paced and entertaining journey through the history, present, and future of these important yet mysterious cosmic bodies. From ancient times, humans have been fascinated by 'broom stars' and 'blazing scimitars' lighting up the sky and moving against the fixed background of stars. The Great Comets of our time still receive in-depth attention - ISON, Hale-Bopp, Hyakutake, West, and others - while recent spacecraft encounters offer amazing insight into the earliest days of the solar system. In this guide you will discover the cutting-edge science of what comets are, how they behave, where they reside, how groups of comets are related, and much more. The author carefully explores the ideas relating comets and life on Earth - and the danger posed by impacts. He finishes with practical, how-to techniques, tips, and tricks on how to successfully observe comets and even to capture your own images of them.
