What type of telescope is best for beginners? Can I use my camera to take photographs through a telescope? How good are the new computerized telescope mounts? What charts, books, software and other references do I need? These questions are asked time and again by enthusiastic new amateurs as they take up recreational astronomy.
But accurate, objective and up-to-date information can be hard to find. Throughout the 1990s, the first edition of The Backyard Astronomer's Guide established itself as the indispensable reference to the equipment and techniques used by the modern recreational stargazer. Now, authors Terence Dickinson and Alan Dyer have produced an expanded and completely updated edition that again sets the standard for accessible and reliable information on one of the world's most popular hobbies.
Dickinson and Dyer both full-time astronomy writers bring decades of experience to their task. They explain why telescopes often perform much differently from what the novice expects. They recommend the accessories that will enhance the observing experience and advise what not to buy until you become more familiar with your equipment. They name brands and sources and compare value so that you can be armed with the latest practical information when deciding on your next purchase. Sections on astrophotography, daytime and twilight observing, binocular observing and planetary and deep-sky observing round out this comprehensive guide to personal exploration of the universe. Dickinson and Dyer's elegant yet straightforward approach to a complex subject makes this book an invaluable resource for astronomers throughout North America.
With morethan 500 color photographs and illustrations, The Backyard Astronomer's Guide is also one of the most beautiful and user-friendly astronomy books ever produced.
About the author:
Terence Dickinson is the author of the best-selling guidebook NightWatch and 13 other books, among them The Universe and Beyond, Splendors of the Universe, Summer Stargazing and Exploring the Night Sky. He is also editor of the Canadian astronomy magazine SkyNews and is an astronomy commentator for Discovery Channel Canada.
Alan Dyer is program producer at the Calgary Science Centre Planetarium and a contributing editor to Sky & Telescope magazine. He is widely regarded as an authority on commercial telescopes, and his evaluations of astronomical equipment appear regularly in major North American astronomy magazines.
The text builds though each successive chapter, describing today's plethora of binoculars, telescopes, mounts, eyepieces, and other accessories. We then move on to delve deeply into everything of interest in the sky, from the planets to deep-sky objects. The detailed yet accessible explanation of celestial mechanics should be required reading for everyone. The third part introduces digital astrophotography. Yes, digitalit starts out by stating that film is dead. This new section covers everything you need to get started taking pictures, including some useful parts of Adobe Photoshop. The Backyard Astronomer's Guide closes with a set of beautifully rendered charts of the Milky Way by Glenn LeDrew. Opposing pages display a color version and a labeled, black-on-white version plotted to magnitude 9. Dickinson and Dyer have brought their excellent guide further into the 21st century. I can't recommend it highly enough.

Chapter One: Amateur Astronomy Comes of Age
There is something deeply compelling about the starry night sky. Those fragile flickering points of light in the blackness beckon to the inquisitive mind. So it was in antiquity, and so it remains today.
But only in the past decade have large numbers of people decided to delve into stargazing recreational astronomy as a leisure activity. Today, more than half a million people in North America call themselves amateur astronomers.
The magic moment when you know you're hooked usually comes with your eye at a telescope eyepiece. It often takes just one exposure to Saturn's stunningly alien, yet serenely beautiful ring system or a steady view of an ancient lunar crater frozen in time on the edge of a rumpled, airless plain.
Naturalists of the Night
19th-century poet and essayist Ralph Waldo Emerson once wrote: "The man on the street does not know a star in the sky." Of course, he was right then and now. Well, almost. In recent years, a growing number of people want to become acquainted with the stars. Sales of astronomy books, telescopes and astronomy software have reached all-time highs. More people than ever before are enrolling in the astronomy courses offered by colleges, universities and planetariums. Summer weekend gatherings of astronomy enthusiasts for telescope viewing and informative talks (known among the participants as "star parties") now attract thousands of fans. There is no mistaking the signals: Astronomy has come of age as a mainstream interest and recreational activity.
Not coincidentally, the growth of interest in astronomy has paralleled the rise in our awareness of the environment. The realization that we live on a planet with finite resources and dwindling access to wilderness areas has generated a sharp increase in activities which involve observing and appreciating nature: birding, nature walks, hiking, scenic drives, camping and nature photography. Recreational astronomy is in this category too. Amateur astronomers are naturalists of the night, captivated by the mystique of the vast universe that is accessible only under a dark sky.
In recent decades, the darkness that astronomy enthusiasts seek has been beaten back by the ever-growing domes of artificial light over cities and towns and by the increased use of security lighting everywhere. In many places, the luster of the Milky Way arching across a star-studded sky has been obliterated forever. Yet amateur astronomy flourishes as never before. Why? Perhaps it is an example of that well-known human tendency to ignore the historic or acclaimed tourist sights in one's own neighborhood while attempting to see everything when traveling to distant lands. Most people now perceive a starry sky as foreign and enchanting rather than something that can be seen from any sidewalk, as it was when our grandparents were young.
That is certainly part of the answer, but consider how amateur astronomy has changed in two generations. The typical 1960s amateur astronomer was usually male and a loner, with a strong interest in physics, mathematics and optics. In high school, he spent his weekends grinding a 6-inch f/8 Newtonian telescope mirror from a kit sold by Edmund Scientific, in accordance with the instructions in Scientfic American telescope-making books. The four-foot-long telescope was mounted on what was affectionately called a plumber's nightmare an equatorial mount made of pipe fittings. In some cases, it was necessary to keep the telescope out of sight to be brought out only under cover of darkness to avoid derisive commentary from the neighbors.
Practical reference material was almost nonexistent in the 1960s. Most of what there was came from England, and virtually all of it was written by one man, Patrick Moore. Amateur astronomy was like a secret religion so secret, it was almost unknown.
Thankfully, that is all history. Current astronomy hobbyists represent a complete cross section of society, encompassing men and women of all ages, occupations and levels of education. Amateur astronomy has finally come into its own as a legitimate recreational activity, not the pastime of perceived lab-coated rocket scientists and oddballs. Indeed, it has emerged as a leisure activity with a certain prestige. Unlike some hobbies, it is not possible to buy your way into astronomy. Astronomical knowledge and experience take time to accumulate. But be forewarned: Once you gain that knowledge and experience, astronomy can be addictive.
Amateur Astronomy Today
Amateur astronomy has become incredibly diversified. No individual can master the field entirely. It is simply too large; it has too many activities and choices. In general, though, amateur astronomers divide fairly easily into three groups: the observers, the techno-enthusiasts and the armchair astronomers. The last category refers to people who pursue the hobby mainly vicariously through books, magazines, lectures, discussion groups or conversations with other aficionados. Armchair astronomers are often self-taught experts on nonobservational aspects of the subject, such as cosmology or astronomical history.
The techno-enthusiast category includes telescope makers and those fascinated by the technical side of the hobby, especially the application of computers to astronomical imaging and telescope use and the application of technological innovations related to amateur-astronomy equipment. It can also involve crafting optics, though this type of telescope making is less prevalent than it was a few decades ago. With the vast array of commercial equipment available today, "rolling your own" is not the common activity it once was.
This book is written primarily for the third kind of amateur astronomer, the observer, one whose dominant interest in astronomy is to explore the visible universe with eye and telescope. Observing, we believe, is what it is all about. The exhilaration of exploring the sky, of seeing for yourself the remote planets, galaxies, clusters and nebulas real objects of enormous dimensions at immense distances is the essence of backyard astronomy.
Getting in Deeper
Amateur astronomy can range from an occasional pleasant diversion to a full-time obsession. Some amateur astronomers spend more time and energy on the hobby than do all but the most dedicated research astronomers at mountaintop observatories. Such "professional amateurs" are the exception, but they are indeed the true amateur astronomers that is, they have selected an area which professional astronomers, either by choice or through lack of human resources, have neglected. They are, in the purest sense, amateurs: unpaid researchers.
In the past, such impassioned individuals were often independently wealthy and able to devote much time and effort to a single-minded pursuit. This is seldom the case anymore. For instance, Australian Robert Evans is a pastor of three churches, has a family with four daughters and is by no means a man of wealth or leisure. Yet he has spent almost every clear night since 1980 searching for supernovas in galaxies up to 100 million light-years away. He discovered 18 within a decade more than were found during the same period by a team of university researchers using equipment designed exclusively for that purpose.
Similarly, most bright comets in recent years have been found by committed amateur astronomers. However, the persistent supernova or comet hunter represents just a tiny fraction of those who call themselves amateur astronomers. The vast majority at least 99 percent are more accurately described as recreational backyard astronomers. Although this term has not gained wide usage, it more precisely describes what most amateur astronomers do. They are out enjoying themselves under the stars, engaging in a personal exploration of the universe that has no scientific purpose beyond self-edification. It's challenging and

Anyone interested in what goes on 'out there' -- and that includes most of us -- should read 'Backyard Astronomer's Guide' before plunking down any money on binoculars, telescopes, eyepieces, or surplus Saturn V rockets. The proud papa of a new telescope, I had about 50 questions that were apparently unanswerable, such as, How much magnification can I get with my 'scope, and how do I increase the optical power without degrading the image quality; Why do stars look twinkly and fuzzy, instead of the prescribed pinpoint of light; How do you decide on a good set of binoculars; and, how do I test and fine-tune the optics of my telescope? And then I found this book. 'Backyard' answers all those questions and more. Messieurs Dickinson and Dyer apparently felt that there were enough star guides and atlases; what was needed was something that would tell people in practical terms how to choose, use and care for the equipment necessary to see all that stuff out there. That's a huge order, and it would have been easy to become bogged down in details that would have rendered the book obsolete before it even went to press. Astro-technology is like everything else, moving at almost the speed of light. But by focusing on the core principles and basics, while periodically revising and updating hardware specs and models, the authors have dodged the technology trap and created a book that will remain a valuable guide for many years to come. The book immediately saved me a wad of cash: I had been thinking about buying a good zoom eyepiece. 'Backyard' states emphatically that the words 'good' and 'zoom eyepiece' don't go together. 'Nuff said. With its comparative tables on everything from magnitude scale to eyepieces and filters, its richly detailed explanations of how equipment works and how to work it, and its huge number of photos, charts and drawings, 'The Backyard Astronomer's Guide' is truly the Boy Scout Handbook of amateur astronomy. It is one of my most prized books on astronomy.
Great for all types of observing of the night sky. A much more advanced version of nightwatch. I use it when I am out with my 8 inch telescope.
I learned a lot from this book! It's full of info that's written in an easily understood fashion. I benefitted greatly from the section on setting circles, R.A. and declination and other confusing topics novice astronomers face. It's worth the dough, folks.
