The Cambridge Double Star Atlas is back! It is the first and only atlas of physical double stars that can be viewed with amateur astronomical instruments. Completely rewritten, this new edition explains the latest research into double stars, and looks at the equipment, techniques and opportunities that will enable you to discover, observe and measure them. The target list has been completely revised and extended to 2500 binary or multiple systems. Each system is described with the most recent and accurate data from the authoritative Washington Double Star Catalog, including the HD and SAO numbers that are most useful in our digital age. Hundreds of remarks explain the attributes of local, rapidly changing, often measured or known orbital systems. The color atlas charts by Wil Tirion have been updated to help you easily find and identify the target systems, as well as other deep-sky objects. This is an essential reference for double star observers.

The Cambridge Star Atlas covers the entire sky, both northern and southern latitudes, in an attractive format that is suitable for beginners and experienced astronomical observers. There is a series of monthly sky charts, followed by an atlas of the whole sky, arranged in 20 overlapping full colour charts. Each chart shows stars down to magnitude 6.5, together with about 900 non-stellar objects, such as clusters and galaxies, which can be seen with binoculars or a small telescope. There is a comprehensive map of the Moon's surface, showing craters and other named features. Wil Tirion is the world's foremost designer of astronomical maps. For this new edition he has devised improved versions of all the charts, and the text and star data have been completely revised based on the latest information. Clear, authoritative and easy-to-use, The Cambridge Star Atlas is an ideal reference atlas for sky watchers everywhere.

Ideal for astronomers worldwide, the fourth edition of this classic atlas features new Moon maps, new data and enhanced charts.

Modern telescopes of even modest aperture can show thousands of double stars. Many are faint and unremarkable but hundreds are worth searching out. Veteran double-star observer Bob Argyle and his co-authors take a close-up look at their selection of 175 of the night sky's most interesting double and multiple stars. The history of each system is laid out from the original discovery to what we know at the present time about the stars. Wide-field finder charts are presented for each system along with plots of the apparent orbits and predicted future positions for the orbital systems. Recent measurements of each system are included which will help you to decide whether they can be seen in your telescope, as well as giving advice on the aperture needed. Double star observers of all levels of experience will treasure the level of detail in this guide to these jewels of the night sky.

Using the latest methods in digital photography and image processing, The Cambridge Photographic Star Atlas presents the whole sky through large-scale photographic images with corresponding charts. Each double-page spread shows a section of the night sky and is accompanied by an inverted chart highlighting and naming double stars, variable stars, open clusters, galactic and planetary nebulae, globular clusters, and galaxies. The 82 large-scale charts, with a scale of 1° per cm, identify over 1500 deep-sky objects and 2500 stars. Providing a giant mosaic of the entire sky, this unique atlas is unparalleled in detail and completeness, making it indispensable for visual observers and astrophotographers.

This magnificent atlas contains the most attractive and interesting double and multiple stars for viewing with binoculars and telescopes. It is a must-have for stargazers who want to explore these fascinating objects. The first modern star atlas devoted to double and multiple stars, it plots over 2000 selected pairs of stars, each labeled with discoverer, catalog, and/or observatory designations. A superb introduction to this important class of celestial objects, it is spiral bound and printed in red-light friendly colours, making it ideal for use in the field. Written by experienced observer James Mullaney, and beautifully illustrated by renowned celestial cartographer Wil Tirion, it provides an easy-to-use 'celestial roadmap' to locate and identify double and multiple stars. Other deep-sky objects such as star clusters, nebulae, and galaxies are also included, and are color-coded for easy recognition and identification, making this an all-purpose observing reference.

This catalog of dounle stars is among the most comprehensive ever printed. With over 2,100 star pairings listed with coordinates, color, and interesting information about every pair, Double Stars for Small Telescopes is an essential addition to the library of every astronomy enthusiast. 248 pages, 8 1/2 x 11 invhes, softcover.

Written specially for practical amateur astronomers who not only want to observe, but want to know and understand the details of exactly what they are looking at. Presents an up-to-date detailed description of the objects, their physics and their evolution (part one); and then (part two) to consider how to observe and record them successfully. Delivers a wealth of information for all levels of amateur observers, from the beginner to the experienced; it is equally fascinating for practical astronomers, and also for those who simply want to find out more about these unusual star systems.

The Observer's Sky Atlas contains star charts and information for all those who observe the night sky with unaided eyes, with binoculars, or with small telescopes, and also for those who just wish to look at constellations and interesting objects. Equally useful for the beginning observer and the old hand, the atlas presents: -a short introduction into observing the sky and a thorough description of the star charts and tables - clearly arranged charts of all the stars visible with the unaided eye (up to 6th magnitude) - enlarged chart sections for binocular observation, highlighting 250 interesting nebulae, galaxies, and stellar clusters (to magnitude 9) - a catalog of more than 1000 objects that takes into account the far-reaching measurements of Hipparcos Satellite published in 1997 - tables of predicted separations of binary stars until the year 2015 The Observer's Sky Atlas is an indispensable and handy companion for every observer. It has appeared in four languages. From reviews of the first edition: , .." the most informative little sky guide in the business" "Astronomy "

This guide charts the positions of over 1,000 stars and celestial objects, arrayed in easy-to-read maps. It includes a detailed introduction to stargazing, with explanations of the celestial sphere, coordinates, time, star names and other basic concepts. The author catalogs a list of eclipses of the sun and moon through the year 2012, and also supplies a complete list of constellation names and symbols. Fourteen color maps show both polar and equatorial projections of the sky. With additional data on the location of variable stars, the brightest stars, and clusters, this book is worth taking on your next nighttime sojourn across the sky.
