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 and read online ebook David Levy's Guide to Observing Meteor Showers write by David H. Levy. This book was released on 2008. David Levy's Guide to Observing Meteor Showers available 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.
