Amateur astronomers of all expertise from beginner to experienced will find this a thorough star cluster atlas perfect for easy use at the telescope or through binoculars. It enables practical observers to locate the approximate positions of objects in the sky, organized by constellation. This book was specifically designed as an atlas and written for easy use in field conditions. The maps are in black-and-white so that they can be read by the light of a red LED observer's reading light. The clusters and their names/numbers are printed in bold black, against a "grayed-out" background of stars and constellation figures. To be used as a self-contained reference, the book provides the reader with detailed and up-to-date coverage of objects visible with small-, medium-, and large-aperture telescopes, and is equally useful for simple and computer-controlled telescopes. In practice, GO-TO telescopes can usually locate clusters accurately enough to be seen in a low-magnification eyepiece, but this of course first requires that the observer knows what is visible in the sky at a given time and from a given location, so as to input a locatable object. This is where "The Observer's Guide to Star Clusters" steps in as an essential aid to finding star clusters to observe and an essential piece of equipment for all amateur astronomers.

Marvel at the wonders of the Universe, from stars and planets to black holes and nebulae, in this exploration of our Solar System and beyond. Universe opens with a look at astronomy and the history of the Universe, using 3D artworks to provide a comprehensive grounding in the fundamental concepts of astronomy, including the basic techniques of practical astronomy. The core of the book is a tour of the cosmos covering the Solar System, the Milky Way, and galaxies beyond our own. Explanatory pages introduce different celestial phenomena, such as galaxies, and are followed by catalogues that profile the most interesting and important examples. A comprehensive star atlas completes the picture, with entries on each of the 88 constellations and a monthly sky guide showing the night sky as it appears throughout the year as viewed from both the northern and southern hemispheres.

Cometography is the most complete and comprehensive collection of data on comets available. It comes in four self-contained sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides nontechnical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet and identified using this book. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

The only small, popular book on the important subject of ancient calendars.
The study of heavenly cycles is common to most ancient cultures. The ancient Egyptians, Chinese, and Babylonians all tried to make sense of the year. But it fell to the later Mesoamerican Maya to create a series of calendars that could be cross referenced. In doing so, the Maya discovered many strange numerical harmonics. Their lunar calendar was extremely accurate--far more so than the Greek Metonic cycle; they tracked Venus to an accuracy of less than a day in five hundred years and their tables could have been used to predict eclipses seven hundred years in the future. This book will provide a much needed compact guide to the Mayan calendar systems as well as covering the essentials of calendar development throughout the world.

Richly illustrated with a luminous and informative collection of maps, photographs, and graphics, this atlas is the perfect companion for exploring the wonders of the universe as viewed from Earth. This expansive illustrated atlas invites readers to roam the night sky for constellations, planets and moons, eclipses, comets and meteor showers, auroras, and deep-sky treasures including nebulae and galaxies-many visible to the naked eye and all with binoculars or a backyard telescope. Beginning with basic space science and including a complete set of night sky maps for all four seasons in the Northern and Southern Hemispheres, this fascinating book guides the reader toward the most rewarding observations. A unique chapter on astro-tourism highlights ancient observatories, dark-sky preserves, and other global destinations for the sky-seeking traveller; a final chapter details current and future space missions and what they might discover. Richly illustrated with awe-inspiring imagery-including photos from space missions and telescopes, science-based artists' interpretations, and explanatory graphics-the book also contains 170 maps and charts of planets, moons, and constellations, from Earth's moon to moons of Saturn. Practical advice throughout helps readers see what they have been reading about, building key observational skills such as "star hopping" from easy-to-find stars to fainter deep-sky objects and focusing on "deep sky treasures:" areas rich in observable phenomena. Approachable and authoritative, gorgeous and fascinating, this large-format illustrated atlas will intrigue all who love to gaze up in wonder at the night sky-and find themselves wanting to know more.

The interstellarum Deep Sky Atlas set a new high standard for modern celestial cartography. The same team now presents the interstellarum Deep Sky Guide, its unique observing companion. Taking an intuitive visual approach, for each spread of the Atlas, the Guide focuses on carefully selected objects, either as colored composite POSS plates or through the authors' own eyepiece sketches. They allow you to estimate the visibility of features in the telescope while planning observations. Stars and other objects in the vicinity are highlighted, so they also serve as finder charts at night. An index map on each spread allows you to quickly find each object's location in the Atlas. The interstellarum Deep Sky Guide takes all the hassle out of preparing for observing sessions - there's no need to print star charts or photos. Simply grab your Atlas and your Guide, and go observe!

Planetary scientist and educator Ken Coles has teamed up with Ken Tanaka from the United States Geological Survey's Astrogeology team, and Phil Christensen, Principal Investigator of the Mars Odyssey orbiter's THEMIS science team, to produce this all-purpose reference atlas, The Atlas of Mars. Each of the thirty standard charts includes: a full-page color topographic map at 1:10,000,000 scale, a THEMIS daytime infrared map at the same scale with features labeled, a simplified geologic map of the corresponding area, and a section describing prominent features of interest. The Atlas is rounded out with extensive material on Mars' global characteristics, regional geography and geology, a glossary of terms, and an indexed gazetteer of up-to-date Martian feature names and nomenclature. This is an essential guide for a broad readership of academics, students, amateur astronomers, and space enthusiasts, replacing the NASA atlas from the 1970s.

As interest in astrology continues to grow, so too have the sales of this accurate working tool. Raphael's Ephemeris continues to fill the astrologer's everyday need for pocket reference and is used extensively by professionals and students alike. The Ephemeris is widely recognised in its classic livery and should be displayed by general bookshops, specialised New Age shops and, of course, in every astrology outlet. Longitudes of all the planets for every day of the year. Tables of Houses for London, Liverpool and New York. Complete Lunar and Planetary Aspectarian together with all the necessary data for casting horoscopes North and South of the Equator.

Raphael's Astronomical Ephemeris has been published every year for well over 100 years. Renowned for its accuracy, it is respected the world over as the number one portable planetary guide and aspectarian.
