Only guide to live observation of deep space, utilizing modern image enhancement techniques (image intensifiers and CCD video monitors) Detailed information supplied on the image intensifiers and CCD video monitors Explains how to select and prepare sites for live viewing.
Many lights and other objects in the sky go unrecognised, or at least are little understood by those observing them. Such things range from the commonplace like rainbows and meteors, to the distinctly unusual like the green flash and ball lightning. And there is still a residuum of objects that remain unidentified by the watcher – classed generally as ‘UFOs’, a description which today has connotations of the mysterious, even of extraterrestrial visitors. The first part of this book is an identification guide, very much like the "plant identifier" sections found in a good gardening or botany book. It allows quick (and structured) identification of known aerial phenomena, whether at night or during the day. The objects thus found are referenced to the second part of the book... The second part gives a full description, physical explanation, and where relevant notes on observing and photographing the various phenomena. Some will need optical aids such as binoculars or telescopes, but the main thrust of the book is identification and explanation rather than imaging. The final chapter approaches UFOs from a scientific standpoint, particularly the way in which human perception and often preconception affects the outcome. It does however finish with a short section on "extraterrestrial UFOs", emphasising the burden of proof aspect and touching on the scientific theories of life on other worlds and the improbability of visitors.
T. Plotner, The Night Sky Companion, DOI 10. 1007/978-0-387-79509-6_1, 1 Springer ScienceþBusiness Media, LLC 2009 2 TheNightSkyCompanion Welcome,fellowtravelertothestars!Forthenextyearwewilltakeajourneytogetheracrossthenight sky. In these pages you will find lunar features, planets, meteor showers, single and multiple stars, open and globular clusters, as well as distant galaxies. There will be astronomy history to explore, famous astronomers to meet, and science to learn. You’ll find things here for those who enjoy stargazing with just their eyes, binoculars, or even the largest of telescopes! Although these observing tips are designed with all readers in mind, not everyone lives in the same time zone—or the same hemisphere—and certainly no one has clear skies every night. But no matter where you live, or who you are, it is my hope that somewhere here you find something of interest to keep you looking up! LearningtheNightSky If you are new to astronomy, it might seem difficult to learn all those stars. Relax! It’s much easier than you think. Just like moving to a new city, everything will seem unfamiliar at first, but with a little help from some maps, you’ll soon be finding your way around like a pro. Once you become familiar with the constellations and how they appear to move across the night sky, the rest is easy. If you do not have maps of your own, try visiting your local library or one of many online sites thatcangeneratethem.

Climate change is acknowledged as being one of the most important areas of research today. Increasing global temperatures will impact all of us to a greater or lesser extent. From the point of view of research it is an enormously important and complex subject. However, little attention is paid to its relationship to astronomy, the sun in particular but not exclusively. Though directed at an astronomically inclined readership, and providing some less well-known astronomically related information, studies and concepts, this book will also appeal to a broader public, who need to understand the subject of climate change and learn of all the various theories and possible solutions.
Over the last 15 years or so there has been a huge increase in the popularity of astrophotography with the advent of digital SLR cameras and CCD imagers. These have enabled astronomers to take many images and, indeed, check images as they scan the skies. Processing techniques using computer software have also made ‘developing’ these images more accessible to those of us who are ‘chemically challenged!’ And let’s face it – some of the pictures you see these days in magazines, books, and on popular web forums are, frankly, amazing! So, why bother looking through the eyepiece you ask? Well, for one thing, setting up the equipment is quicker. You just take your ‘scope out of the garage or, if you’re lucky enough to own one, open the roof of your observatory, align the ‘scope and off you go. If you have an equatorial mount, you’ll still need to roughly polar align, but this really takes only a few moments. The ‘imager’ would most likely need to spend more time setting up. This would include very accurate polar alignment (for equatorial mounts), then finding a guide star using his or her finder, checking the software is functioning properly, and c- tinuous monitoring to make sure the alignment is absolutely precise throu- out the imaging run. That said, an imager with a snug ‘obsy’ at the end of the garden will have a quicker time setting up, but then again so will the ‘visual’ observer.
There are 'voids' obscuring all kinds of objects in the cosmos. Voids may be within an object, or between an object and us. Dark Nebulae, Dark Lanes, and Dust Lanes looks out into the deep sky at those apparent dark regions in space, which are among the most compelling telescopic destinations for amateur observers. One famous example is Barnard's dark nebulae - those striking dark clouds set against the background of stars in the Milky Way. But there are countless other less well known examples. These dark regions are often ignored altogether or commented upon only briefly in astronomy books, and it is all too easy to overlook the treasure trove they offer the observer. Dark Nebulae, Dark Lanes, and Dust Lanes is a great source of practical information for observers. Such voids may be successfully observed using conventional observing methods, but they are often far better seen with technologies such as light-pollution filters, CCD video cameras, and image intensifiers. This book explains the optimal ways to observe each object in detail.
The only practical guide to observing truly spectacular astronomical objects from less than perfect locations. The only book to deal in depth with the application of image intensifiers to real-time astronomy. Gives advice on viewing objects, and on making realistic images by drawing or video. Includes extensive catalogs of spectacular objects that can be seen from suburban sites in both hemispheres.

Amateur astronomers who have been disappointed by the results of an observing session can take comfort in the guidance of this book, which advises how to still gain useful experience in seemingly "failed" nights at the telescope. In a world with imperfect seeing conditions, incredible observing sessions are often mixed with less inspiring ones, discouraging the amateur observer. This book is designed to minimize subsequent disappointment for astronomers who encounter a few bad observing sessions, helping novice observers take something worthwhile away each and every time they go out under the night sky, regardless of the observations that were originally planned. Almost every observer remembers his first sight of ringed Saturn, hanging in the blackness of space. Practitioners agree that there is something special about visual observing. Real-time observations at the eyepiece can provide fleeting yet intense feelings that connect us with the universe in unique ways. But when expectations aren't met at the eyepiece, there are other ways to profit from the practice of astronomy. These rewards, though less showy, are well worth cultivating. This is a book that will help the reader see what constitutes a “successful” visual observing session. It explains the nature of the objects that the observer is seeing and advises how best to use their equipment. There are many hints and tips about how best to locate, recall, and record observations, including suggestions for trips to areas where there are dark skies and to public observatories. Amateur astronomy is a journey from the urban backyard all the way to dark rural skies, and with this guide the journey can be smooth.
Observing the Moon is a definitive work, written as a reference book for anyone seriously interested in the Moon and its geology. It is of course a perfect companion for practical observers. Detailed and extensively illustrated chapters catalog ail the interesting lunar features visible in modest telescopes. They are preceded by a crash course in modern lunar geology - based on the vast amount we have learned during and since the Apollo missions - and are followed by chapters on photographic and CCD imaging, drawing and lunar topography. A CD-ROM accompanies this book and contains an atlas of lunar images and much more. The CD-ROM requires a PC running Windows 3.1 or higher, a minimum of 16MB (Windows 3.1), 64MB (Windows 95 up) of memory and a 2x or faster CD-ROM player.
Here is a one-volume guide to just about everything computer-related for amateur astronomers! Today’s amateur astronomy is inextricably linked to personal computers.

Planetarium software provides information and an easy interface for telescopes. The Internet offers links to other astronomers, information, and software. The list goes on and on. Find out here how to choose the best planetarium program: are commercial versions really better than freeware? Learn how to optimise a go-to telescope, or connect it to a lap-top. Discover how to choose the best webcam and use it with your telescope. Create a mosaic of the Moon, or high-resolution images of the planets... Astronomy with a Home Computer is designed for every amateur astronomer who owns a home computer, whether it is running Microsoft Windows, Mac O/S or Linux. It doesn’t matter what kind of telescope you own either - a small refractor is just as useful as a big "go-to" SCT for most of the projects in this book.
Stephen O'Meara's new and exciting observing guide spotlights an original selection of 109 deep-sky objects that will appeal to sky-watchers worldwide. His 'hidden treasures' include a wonderful assortment of galaxies, open clusters, planetary nebulae and more, all of which have been carefully chosen based on their popularity and ease of observing. None of these objects are included in either the Messier or the Caldwell catalogs, and all are visible in a 4-inch telescope under dark skies. Stunning photographs and beautiful drawings accompany detailed visual descriptions of the objects, which include their rich histories and astrophysical significance. The author's original finder charts are designed to help observers get to their targets fast and efficiently.

With the advent of CCDs and webcams, the focus of amateur astronomy has to some extent shifted from science to art. Visual work in astronomy has a rich history. Today, imaging is now more prominent. However there is still much for the visual amateur astronomer to do, and visual work is still a valid component of amateur astronomy. Paul Abel has been addressing this issue by promoting visual astronomy wherever possible – at talks to astronomical societies, in articles for popular science magazines, and on BBC TV’s The Sky at Night. Visual Lunar and Planetary Astronomy is a comprehensive modern treatment of visual lunar and planetary astronomy, showing that even in the age of space telescopes and interplanetary probes it is still possible to contribute scientifically with no more than a moderately-priced commercially made astronomical telescope. It is believed that imaging and photography is somehow more objective and more accurate than the eye, and this has led to a peculiar “crisis of faith” in the human visual system and its amazing processing power. But by analyzing observations from the past, we can see how accurate visual astronomy really is! Measuring the rotational period of Mars and making accurate lunar charts for American astronauts were all done by eye. The book includes sections on how the human visual system works, how to view an object through an eyepiece, and how to record observations and keep a scientific notebook. The book also looks at how to make an astronomical, rather than an artistic, drawing. Finally, everything here will also be of interest to those imagers who wish to make their images more scientifically applicable by combining the methods and practices of visual astronomy with imaging.
