Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time
Anyone alive in the eighteenth century would have known that “the longitude problem” was the thorniest scientific dilemma of the day—and had been for centuries Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution. The scientific establishment of Europe—from Galileo to Sir Isaac Newton—had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution—a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest, and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world. .

Deep Sky Observing: The Astronomical Tourist (Patrick Moore's Practical Astronomy Series)
Steve Coe has been watching the deep sky from locations near his home in Arizona for almost 20 years. During that time he has accumulated a wealth of knowledge, observations, hints and tips that will help every deep sky observer, regardless of experience This, his first book, gives detailed practical advice about how to find the best observing site, how to make the most of the time spent there, and what equipment and instruments to take along. There are comprehensive lists of deep sky objects of all kinds, along with Steve's own observations describing how they look through telescopes with apertures ranging from 8 to 36 inches (0.2 - 0.9 m). Most of all, this book is all about how to enjoy astronomy. Steve's enthusiasm and sense of wonder shine through every page as he invites you along on a tour of some of the most beautiful and fascinating sites in the deep sky..

Light Pollution: Responses and Remedies (Patrick Moore's Practical Astronomy Series)
Light-pollution is the modern scourge of optical astronomy. More and more observing sites are being lost as the glare of city lighting blots out the night sky. Professional astronomical observatories are located far from cities, but amateur astronomers often do not have this luxury. This book considers the two available strategies open to astronomers - get rid of the light pollution by lobbying Authorities and Standards Organisations, and minimise its effects by using the correct instrumentation. The book contains an extensive detailed catalogue of deep-sky and other objects that - despite what one might believe - can be seen from variously light-polluted sites, for practical observers..

Textbook on Spherical Astronomy
This well-established textbook gives a general but comprehensive introduction to positional astronomy. Originally based on the author's lecture courses at Cambridge University, it is intended primarily for undergraduates, but, due to its comprehensive nature, it is a very useful reference text for research workers in many branches of astronomy and space physics. The author considers the night sky as the celestial sphere and powerfully exploits the methods of spherical geometry. Most problems in which the precise determination of a heavenly body's position in the sky is important are considered in theoretical detail, and the necessary formulae are derived to a precision that is sufficient for all but the most specialist purposes. The present revision has ensured that the terminology and treatment correspond precisely to current astronomical practice. A guiding principle has been to re-establish compatibility with the Astronomical Ephemeris and, to a lesser extent, with the fuller explanations of the Explanatory Supplement to the Astronomical Ephemeris and the American Ephemeris and Nautical Almanac. Fairly frequent comments added to the text indicate the sometimes modified relevance of the subject matter to modern astronomy. A number of additional exercises help to illustrate the new material..

Solar Observing Techniques (Patrick Moore's Practical Astronomy Series)
The Sun is the closest star to Earth, and the only one we can observe in any sort of detail. As such it is a fascinating field of study, and one that is well-suited to amateur astronomers - the Sun is close enough to need little magnification. It also has the practical advantage, unlike every other astronomical object, of being visible in the daytime! During solar eclipses, there are momentary chances to observe and photograph some spectacular and scientifcally interesting sights. Studying the Sun nonetheless needs specialist knowledge. Safety is paramount, as without the right precautions the heat and light of the Sun would instantly blind the observer. But given the right techniques, the Sun is a rewarding subject for amateur astronomers: in this book, Professor Chris Kitchin provides all the information needed for safe solar observing..
