Astronomy is among the oldest recorded human activities, and the planets have
always held a special fascination. As seen by the unaided eye, their motion
across the night sky is the only way in which the heavens appear to change
Author: Dominic Ford
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.

A practical introduction to our "corner" of the universe. Aimed at users of binoculars and small to medium telescopes, Solar System Observer's Guide describes how to observe not only the planets but also the moon, sun, comets, meteors, asteroids, and all other celestial objects found within our Solar System. Each chapter is devoted to a different object and explains how and when to find the object, how to observe it, what to expect to see, and how to record observations. Photographs, sketches, and digital images by both amateur and professional astronomers illustrate the book's pages. The easy-to-use guide also features: Best observation dates over the next 10 years Special events, such as eclipses and transits Up-to-date equipment and techniques Tips on dealing with difficult viewing conditions When to use special equipment More than 100 photographs, maps, and artworks Appendices, including notable phenomena to 2015 Glossary and resources. Suitable for use in the northern and southern hemispheres, Solar System Observer's Guide is a practical and colorful introduction to observing our universe.

All three volumes sold as a combined set for a one-time purchase! This comprehensive three-volume set takes you on an incomparable journey of our closest celestial neighbor. Not since the golden age of 19th-century lunar guidebooks has one author managed to cover the Moon in such detail as this all-in-one handbook. Volume 1 begins with a section on the Moon’s place in human history, mythology and lore, before gravitating closer to the Moon itself through scientific sections on the Earth-Moon system, lunar motions and cycles. Following these are technical chapters on how to purchase, use and care for lunar observing and photography equipment. Techniques for observing the Moon (both with the naked eye and optical instruments) are detailed as the reader approaches the Moon’s surface on this visual tour-de-force. A close-up exploration of the Moon is the result. The “crater-hop” chapters in Volumes 1 and 2 discuss the physical aspects of the Moon’s features, offering brief biographical information on the person for whom the feature is named, as well as how each individual was involved in the development of science and selenography from ancient to modern times. Volume 3 contains a plethora of useful appendices that cover a range of topics, from catalogues of lunar features such as nearside lunar domes to a comprehensive list of publishers and observing organizations. Luna Cognita goes far beyond any recent work in both breadth and depth of coverage on the Moon. Written in an accessible, engaging manner for readers of all backgrounds and levels of expertise, this handbook is thus an invaluable resource for anybody who looks up at the glowing sphere in the night sky and wants to learn more about the “Known Moon.”

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.
