In an astronomical world that's becoming increasingly dominated by computerised 'goto' telescopes, here's a book that shows the budding amateur that the old method of 'star-hopping' is still a valid and satisfying alternative: Turn left at Orion.Many budding observers are daunted by the prospect of 'learning the sky' well enough to find their way to those elusive deep sky objects. And even when the desired target is perfectly centred in the eyepiece, it's often so difficult to recognise that the search resumes unnecessarily. When a positive identification is finally made, one wonders if the exercise was worth all the effort. Why? Because, visually, they don't look anything like their flattering portrait photographs.The end result is frustration and disappointment.Well, here's the book that changed my astronomical life: it taught most of the major constellations, and plenty of minor ones to boot; it showed me how to star-hop to the more interesting deep sky objects within them; and it also changed my expectations of what I would see when I got there.Literally, this is a 'star-hopping made easy' bible.The book works on the assumption that the reader is prepared to learn up front just a few of the major constellations. The Big Dipper, (or Plough to the Brits, or 'Pluff' to them southerners), is one that most people can recognise straight off. But it helps to be able to spot the big square of autumn's Pegasus, winter's unmistakable Orion the hunter, spring's sickle-necked Leo the Lion, and the big cross of summer's Cygnus the swan. These are all good starting points, and won't cost much effort to learn beyond a cricked neck.The book feels like it's been written from copious notes acquired during many years of practical observing. There's a section per seasonal, with two pages devoted to each particular object. And the objects really are a good primer for the northern deep sky: nebulas, globular clusters, open clusters aplenty of course, some galaxies, and a good sprinkling of those oft neglected double stars. On the left page you'll find a typical upside-down finder-scope view of the target area, plus a description of which stars to use to guide you there. On the right page is a typical left-to-right telescopic view of the object itself, plus good textual descriptions.And here's the clever bit: all of the illustrations are beautifully hand-drawn to show truthfully how they appear at the eyepiece; none of those misleading full colour observatory-type photographs here: what you see is what you, er, see. Fear not if an illustration fails to take your fancy; keep turning the page until one catches your eye.So how does it work under the night sky?Well, it works beautifully. Turn to the correct page, and locate the general target area using your (ahem) marginal knowledge of the constellations, then visually hop from star to star as advised. Aim your telescope, then switch to the finder-scope to identify the exact location. Slip in an eyepiece of about the

A highly effective work, for beginners and teachers.

In the Belmont Society, Turn Left at Orion is one of those enduring staples that eventually becomes an icon of eminent preservation. It's been handed down through the membership as a benchmark of highly valued works, which we've long ago earmarked for its educational value. Back on the lecture circuit some years ago, this was one of those books we always recommended as "required reading" for the beginner, along with (among others) Sagan's Cosmos, and The Backyard Astronomer's Guide by Dickinson. Each became tremendously popular for different reasons, and each could hold its own as a reference for different levels of interest. Over the years the "List" has grown to include six books, and although none have been added in recent times, a few have come very close (i.e. - O'Meara's Messier Objects deserves Honorable Mention). As a result, Turn Left at Orion remains after all these years, one of the six essential works, which we regard as required reading by the beginning amateur astronomer. Though not part of my personal collection until recently, it has been at my disposal for many years. I keep meaning to review it, but something always comes up, not the least of which was the recent printing of a 3rd edition.The work is co-authored by Guy Consolmagno, a Jesuit Brother at the Vatican Observatory; and Dan M. Davis, professor of geophysics at the State University of New York. Between them they conspired to create a work that reflects a singular passion for viewing celestial objects with small telescopes (emphasis on small). In fact, the combined aperture of both authors' instruments is somewhat less than the singular average among beginning-amateur telescopes. One is a 3.5-inch Cassegrain, and the other is a 2.5-inch refractor. Nevertheless, with these small instruments they were able to create a first-rate work of impressive magnitude. Simplistic means to extraordinary ends.I was introduced to the order of Jesuits as a youngster growing up in New England. Even at that young age I was profoundly inspired by the notion that science could be passionately embraced (and accurately promoted) in concert with unwavering religious faith. Almost any science buff knows full well that astronomy and religion run like oil and water through the veins of history. And because this work represents such a remarkable beacon of parallel encounter, I am somewhat disappointed in myself for not doing this earlier. But now, so much has been said about this book that there seems a trite redundancy in plugging it. Oh well.Pioneers and discoverers like Galileo and Messier were themselves saddled with equipment that can easily be considered pathetic by today's standards (both optically and mechanically). However, countless thousands of celestial objects were acquired, catalogued, and studied using archaic equipment of the sort. The point being, that you don't have to bribe the evening sky with money or fat-free technology to see what it's hiding. You merely need to coax it sligh

The reviews nailed it

I had a telescope sitting in a corner looking pretty but gathering dust for three years, until I found this book. "Turn Left at Orion" has turned me on to amateur astronomy because of its straightforward, assume-nothing presentations. Using this book at my own pace, I've begun to learn the night sky and get excited about using my scope. Even though I live in the city, I find myself gazing skyward every clear night, browsing a now-familiar sky. There are other aids you'll need as an amateur astronomer, but nothing I've seen is more perfect for a beginner.

New telescope? Start here!

Too many amateur astronomy books are haughty, if not insulting, about the mass of small telescopes that people buy or receive as gifts. Sidebars like "Trash Scope Blues" are an example. This book, written by two professional astronomers, points out that the small telescope of today is the magnificent instrument beyond the dreams of Galileo or Messier*. With that foundation in place they proceed to lead you through the night sky to view the most interesting objects for small telescopes. They begin with the deepest coverage of the moon that I have encountered yet. There are separate sections for each phase of the moon detailing highlights of what is unique at that time of the month.Then they tour the night sky, season by season. Their directions to find items of interest don't presume that you know the constellations. Instead, in "Where to Look" they start with the bright, easy to find stars, and from there walk you over to the item. They assist your search by describing what you'll see in the finder scope and the telescope and have illustrations of what you will actually see in the telescope. (Not some picture taken by an observatory or the Hubble telescope.) In "Comments" they describe what you'll see, suggest the eyepiece to use to get the most of the view, and give details about just what that thing is. All objects are given a 1 to 4 telescope rating to help you choose the fun ones first. The Orion Nebula is an exception that receives a 5 telescope rating: easy to find, viewable in city light haze, with different interesting views at low and high power. Of the half dozen astronomy books I've looked over this is the hands down best book for the new owner of a telescope to have. More than any other book, it will help you get the most from your telescope. *Never heard of Messier? Most non-astronomers haven't Charles Messier hunted the skys for comets and kept coming across things that, at first glance, might be a comet. After figuring out that they weren't comets, he kept a record of them so he wouldn't waste time on them again. As it turns out this list contains some of the neatest things to see in the night sky.

The ESSENTIAL book for beginning astronomers

Just starting to look at the night sky with a small telescope or binoculars? Buy this book. I spent many a frustrated night with my new scope, trying in vain to find galaxies and other interesting objects in the heavens. Half a dozen other sky guides were no help -- and the astrophotographs they offered gave me no clue to what I might actually see with my own eyes. "Turn Left at Orion" transformed me from a galaxy hunter to a galaxy finder even while stargazing under light-polluted suburban skies. Clearly and entertainingly written, TLAO never leaves the reader lost and offers interesting background on what you are viewing as well as other essential information such as "How to run a telescope." My copy is now a year old and is the most-used volume in my stargazing library. It's one of those rare books that can be used by a "square one" beginner or a clueless parent trying to show a youngster how to use a telescope yet still will a delight to an amateur astronomer with more experience. Here's a recipe for years of awe-inspiring after-dark entertainment: a small telescope or 7X50 binoculars, a copy of Turn Left at Orion, a red-lens flashlight (so you can refer to the TLAO in the dark without losing your night vision), and clear skies.
