You are holding in your hands, dear Reader, your passport to an exciting cosmic adventure - exploring the universe of double and multiple stars! These are the sky's tinted jewels and waltzing couples, and they are waiting patiently in the darkness of night to dazzle and delight you. This is actually two books in one. The ?rst part surveys the current state of knowledge about double stars - how they are born, evolve and interact, their signi?cance in the cosmic scheme of things,and the valuable insights they provide into such fundamental matters as stellar masses and the ultimate fate of stars.The more we know about these fascinating objects, the more enjoyment we will ul- mately derive from actually viewing them ?rsthand with binoculars and telescopes from our gardens or backyards or ?elds.As Charles Edward Barns stated in his long out-of-print classic 1001 Celestial Wonders, Let me learn all that is known of them, Love them for the joy of loving. For,as a traveler in far countries Brings back only what he takes, So shall the scope of my foreknowledge Measure the depth of their pro?t and charm to me.
Amateur astronomers of all skill levels are always contemplating their next telescope, and this book points the way to the most suitable instruments. Similarly, those who are buying their first telescopes - and these days not necessarily a low-cost one - will be able to compare and contrast different types and manufacturers. This exciting and revised new guide provides an extensive overview of binoculars and telescopes. It includes detailed up-to-date information on sources, selection and use of virtually every major type, brand, and model on today's market, a truly invaluable treasure-trove of information and helpful advice for all amateur astronomers. Originally written in 2006, much of the first edition is inevitably now out of date, as equipment advances and manufacturers come and go. This second edition not only updates all the existing sections of "A Buyer's and User's Guide to Astronomical Telescopes and Binoculars" but adds two new ones: Astro-imaging and Professional-Amateur collaboration. Thanks to the rapid and amazing developments that have been made in digital cameras - not those specialist cool-chip astronomical cameras, not even DSLRs, but regular general-purpose vacation cameras - it is easily possible to image all sorts of astronomical objects and fields. Technical developments, including the Internet, have also made it possible for amateur astronomers to make a real contribution to science by working with professionals. Selecting the right device for a variety of purposes can be an overwhelming task in a market crowded with observing options, but this comprehensive guide clarifies the process. Anyone planning to purchase binoculars or telescopes for astronomy - whether as a first instrument or as an upgrade to the next level - will find this book a treasure-trove of information and advice. It also supplies the reader with many useful hints and tips on using astronomical telescopes or binoculars to get the best possible results from your purchase.
Amateur astronomers - particularly deep-sky observers - are always on the lookout for new observing challenges. The Herschel Objects, and How to Observe Them offers the exciting opportunity of retracing the steps of the greatest visual observer and celestial explorer that ever lived. This is a practical guide to seeing the most impressive of Herschel's star clusters, nebulae and galaxies.
There has never been - and as of the time of submitting this proposal there still isn't - an observer's book devoted to the Herschel objects. The US-based Astronomical League has for several years sponsored a "Herschel Club", reflecting the interest amateur astronomers have in this important but less widely known listing. The Herschel Objects, and How to Observe Them covers more than 600 of the brightest of the objects that Herschel saw, with detailed descriptions and images of 150 to 200 of the very best for viewing with amateur telescopes.
Both beginning/novice amateur astronomers (at the level of Astronomy and Night Sky magazine readers), as well as more advanced amateur astronomers (level of Sky & Telescope) will find this book invaluable and fascinating.
Amateur astronomers are always contemplating the "next telescope up" and this will point the way to the most suitable instrument to which they should aspire. Similarly, those who are buying their first telescope - and these days not necessarily a low-cost one - will be able to compare and contrast different types and makes.
Jim Mullaney is an astronomy writer, lecturer and consultant who has published more than 500 articles and five books: he has also been an editor for Sky & Telescope, Astronomy, and Star & Sky magazines. One of the contributors to Carl Sagan's award-winning Cosmos PBS-Television series, his work has received recognition from such notables as Sir Arthur Clarke, Johnny Carson, Ray Bradbury, Dr. Wernher von Braun, and one of his former students - NASA scientist/astronaut Dr. Jay Apt. He is probably the ideal person to write this book, containing as it does a directory of instruments offered by all the major manufacturers.
This exciting, upbeat new guide provides an extensive overview of binoculars and telescopes. It includes detailed up-to-date information on sources, selection and use of virtually every major type, brand and model of such instruments on today's market - truly an invaluable treasure-trove of information and helpful advice for all amateur astronomers. Also includes details on the the latest released telescope lines, e.g., the 10-, 12-, 14- and 16-inch aperture models of the Meade LX-R series.
