The Observer S Guide To Astronomy Volume 2

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, first published in 1994. 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.

Volume II of a comprehensive three-part guide to celestial objects outside our solar system ranges from Chamaeleon to Orion. Features coordinates, classifications, physical descriptions, hundreds of visual aids. 1977 edition.

This guide provides comprehensive practical information for both beginning and advanced amateur astronomers on how to make scientifically significant observations. The book explains in detail how to observe every conceivable astronomical object--from meteors to distant galaxies. It presents a wide variety of methods ranging from the simplest visual observations, such as making pencil drawings of the surface of the Moon, to the use of highly sophisticated equipment, such as CCD cameras and photoelectric photometers. It also explains how to record and catalog observations using recognized professional terminology and classification schemes. The volume's emphasis throughout is on giving amateur astronomers sound information to use at the telescope. The most effective and efficient techniques are presented so that observers can apply those that are most suitable to their own equipment and degree of experience. This comprehensive survey of practical methods of observation will develop the observational skills of the avid novice and will also satisfy the more demanding needs of the experienced amateur astronomer.

The most detailed guide to observing the deep sky in one volume, now available in paperback.

This is the first of a two-volume set that deal with the entire Milky Way. This first volume looks at what can be seen predominantly from the Northern Skies. In addition to the descriptive text, there are many star charts and maps, as well as the latest up-to-date images made by observatories around the world and in space, as well as images taken by amateur astronomers.

To the naked eye, the most evident defining feature of the planets is their motion across the night sky. It was this motion that allowed ancient civilizations to single them out as different from fixed stars. “The Observer’s Guide to Planetary Motion” takes each planet and its moons (if it has them) in turn and describes how the geometry of the Solar System gives rise to its observed motions. Although the motions of the planets may be described as simple elliptical orbits around the Sun, we have to observe them from a particular vantage point: the Earth, which spins daily on its axis and circles around the Sun each year. The motions of the planets as observed relative to this spinning observatory take on more complicated patterns. Periodically, objects become prominent in the night sky for a few weeks or months, while at other times they pass too close to the Sun to be observed. “The Observer’s Guide to Planetary Motion” provides accurate tables of the best time for observing each planet, together with other notable events in their orbits, helping amateur astronomers plan when and what to observe. Uniquely each of the chapters includes extensive explanatory text, relating the events listed to the physical geometry of the Solar System. Along the way, many questions are answered: Why does Mars take over two years between apparitions (the times when it is visible from Earth) in the night sky, while Uranus and Neptune take almost exactly a year? Why do planets appear higher in the night sky when they’re visible in the winter months? Why do Saturn’s rings appear to open and close every 15 years? This book places seemingly disparate astronomical events into an understandable three-dimensional structure, enabling an appreciation that, for example, very good apparitions of Mars come around roughly every 15 years and that those in 2018 and 2035 will be nearly as good as that seen in 2003. Events are listed for the time period 2010-2030 and in the case of rarer events (such as eclipses and apparitions of Mars) even longer time periods are covered. A short closing chapter describes the seasonal appearance of deep sky objects, which follow an annual cycle as a result of Earth’s orbital motion around the Sun.
