Practical Astronomy Handbooks - Böcker

Observing the Sun is one of the most interesting and rewarding facets of astronomy to which amateurs can contribute. Few areas of science offer as many opportunities to contribute meaningful data. It is the one branch of astronomy that requires only modest equipment and can be pursued during the day. Peter Taylor is a keen and highly experienced observer of the Sun. In this book he explains in a clear and practical way everything that a telescope user needs to know in order to make solar observations. The author draws on his many years of personal experience as a contributor to the Solar Division of the American Association of Variable Star Observers and to the American Sunspot Program. The book deals with the following topics: historical background, choice of equipment for the safe conduct of solar observations, observations of sunspots, and reporting observations. New techniques, such as electronic recording and the operations of radio telescopes, are included. The level of presentation is understandable to anyone with basic astronomical knowledge and some experience in handling a small telescope.

Charles Messier's catalogue of nebulae and star clusters, published in 1784, marked the start of a new era of deep sky astronomy. This tradition of observing galaxies and clusters is kept alive by serious amateur astronomers who study the objects of the deep sky. Nearly all the objects are visible in a small telescope. Many, such as the Crab Nebula and the Andromeda galaxy, are among the most fascinating objects in the universe. Kenneth Glyn Jones has revised his definitive version of Messier's catalogue. His own observations and drawings, together with maps and diagrams, make this a valuable introduction to deep sky observing. Historical and astrophysical notes bring the science of these nebulae to the fore. This is a unique handbook, unlikely ever to be equalled in its completeness and importance to the telescope owner.

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.

Jupiter is an extraordinarily colourful and dynamic planet. Over minutes, one can watch tiny shadows cast by its moons slide over its surface; over days and weeks parades of diverse, giant swirling storms can be seen to move and evolve. It is because of this richness of visual and physical properties that Jupiter has intrigued amateur and professional astronomers and has been the goal of several space missions. This highly illustrated volume provides a comprehensive and accessible account of Jupiter and its satellites. It reviews systematic telescopic observations that have stretched over more than a hundred years, in addition to modern observations and theories, and the wealth of data from the Pioneer, Voyager and Ulysses space missions. As well as a thorough survey of the planet's atmosphere, this volume presents an up-to-date account of our present knowledge of Jupiter's satellites and magnetosphere, at a level accessible to the non-specialist. This volume provides the definitive account of Jupiter for advanced amateur astronomers, professional astronomers and planetary scientists.

How can you find new minor planets, comets and novae? How can you use photoelectric detectors to derive the temperatures of stars? And how can you predict future eclipses and occultations of stars by minor planets? The questions asked by serious amateur astronomers are answered in this authoritative and wide-ranging guide. For each topic, sound practical methods of observation and the scientific background are given to lead you to better observations. Guidelines also show you how to record and catalogue your observations using the recognised 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. It will develop the observational skills of the keen novice and satisfy the more demanding needs of the experienced amateur astronomer.

Harold Hill's lunar portfolio is a unique collection of drawings now published for the first time. Each illustration is supplemented with notes made at the time of observation. Astronomical drawing still has an important place alongside photography in the same way that photography has not supplanted the artist in the fields of botany and ornithology, for example. Indeed, since astronomical images tend to shimmer because of turbulence in the Earth's atmosphere, drawings constructed by an artist who takes advantage of the fleeting moments of perfect vision are often more detailed than photographs. No one can fail to be impressed by the beauty and artistry of this work and, to the initiated, the accuracy and attention to detail is remarkable. This is a book for astronomers, amateur and professional alike, and for those who would simply like to know more about the moon.

High-performance CCD cameras have opened up an exciting new window on the Universe for amateur astronomers. This book provides a complete, self-contained guide to choosing and using CCD cameras. We start with a no-nonsense introduction to how a CCD camera works and just what determines its performance. We are then shown how to use a CCD camera and calibrate accurately the images we obtain. A clear review is then provided of the software available for visualising, analysing and processing digital images. Finally, we are guided through a series of key areas in astronomy where we can make the best use of our CCD cameras. This handy volume is packed with practical tips. It provides a clear introduction to CCD astronomy for novices and an indispensable reference for more experienced amateur astronomers.
