In this study Michael Covington considers the origins and development of the theories of sentence structure formulated by the Modistae, a group of grammarians and logicians who flourished in Paris between about 1270 and 1310. Some of the concepts of the medieval theoretical framework, notably government and dependency, have survived to the present day, and Dr Covington introduces insights from modern grammatical theories where appropriate. Nevertheless his principal aim is not to compare medieval and modern theories, or to provide a comprehensive historical study. Rather, recognising that 'it is the difference as much as the similarity that makes the Modistae interesting', Dr Covington offers an original critical exegesis of these influential theories. The book will be accessible both to linguists who may know little about medieval philosophy and to medievalists who may know little about linguistics.

In the last few years, digital SLR cameras have taken the astrophotography world by storm. It is now easier to photograph the stars than ever before! They are compact and portable, flexible to adapt with different lenses and for telescope use, and above all DSLR cameras are easy and enjoyable to use. In this concise guide, experienced astrophotography expert Michael Covington outlines the simple, enduring basics that will enable you to get started, and help you get the most from your equipment. He covers a wide selection of equipment, simple and advanced projects, technical considerations and image processing techniques. Unlike other astrophotography books, this one focuses specifically on DSLR cameras, not astronomical CCDs, non-DSLR digital cameras, or film. This guide is ideal for astrophotographers who wish to develop their skills using DSLR cameras and as a friendly introduction to amateur astronomers or photographers curious about photographing the night sky.

Based on field notes made by the author during his own career as an amateur astronomer, this unique guide covers both the traditional and novel approaches to studying the night sky. In addition to the more standard techniques, it discusses the latest modern resources available to today's astronomer, such as personal computers, the Internet, and computerized telescopes. It includes practical advice on aspects such as site selection and weather; provides the reader with detailed instructions for observing the Sun, Moon, planets, and all types of deep-sky objects; and it introduces newer specialities such as satellite observing and the use of astronomical databases. The book concludes with detailed information about 200 stars, clusters, nebulae, and galaxies, suitable for viewing with modest-sized telescopes under suburban conditions. Written to complement How to Use a Computerized Telescope, this book will also appeal to astronomers with more traditional equipment.

First published in 1999, this much expanded and updated edition of the best-selling handbook Astrophotography for the Amateur provides a complete guide to taking pictures of stars, galaxies, the Moon, the Sun, comets, meteors and eclipses, using equipment and materials readily available to the hobbyist. In this new edition, the book has been completely revised and now includes new chapters on computer image processing and CCD imaging; expanded advice on choosing cameras and telescopes; completely updated information about the films; a much larger bibliography; and hundreds of new photographs (in colour, and black and white) demonstrating the latest equipment and techniques. Astrophotography for the Amateur has become the standard handbook for all amateur astronomers. This expanded and updated edition provides an ideal introduction for beginners and a complete handbook for advanced amateurs. It will also appeal to photography enthusiasts who can discover how to take spectacular images with only modest equipment.

How to Use a Computerized Telescope is the first handbook that describes how to get your computerized telescope up and running, and how to embark on a program of observation. It explains in detail how the sky moves, how your telescope tracks it, and how to get the most out of any computerized telescope. Packed full of practical advice and tips for troubleshooting, it translates the manufacturers' technical jargon into easy-to-follow, step-by-step instructions, and includes many of the author's tried and tested observing techniques. Early chapters explain how to test your telescope's optics, choose eyepieces and accessories, and diagnose operational problems. The second half of the book then gives detailed instructions for three classic telescopes: the Meade LX200, Celestron NexStar 5 and 8, and Meade Autostar (ETX and LX90). Concentrating mainly on telescope operation and troubleshooting, it is the ideal companion to Celestial Objects for Modern Telescopes, also by Michael Covington.

Digital SLR cameras have made it easier than ever before to photograph the night sky. Whether you're a beginner, nature photographer, or serious astronomer, this is the definitive handbook to capturing the heavens. Starting with simple projects for beginners such as cameras on tripods, it then moves onto more advanced projects including telescope photography and methods of astronomical research. With 80% revised and updated material, this new edition covers nightscapes, eclipses, using cameras with sky trackers and telescopes, and tools for identifying celestial objects and investigating them scientifically. Image processing is discussed in detail, with worked examples from three popular software packages - Nebulosity, Maxlm DL, and PixInsight. Rather than taking a recipe-book approach, Covington explains how your equipment works as well as offering advice on many practical considerations, such as choice of set-up and the testing of lenses, making this a comprehensive guide for anyone involved in astrophotography.

Basic Astrophotography tells you how to take pictures of stars, galaxies, planets, the Moon, the Sun, comets, meteors and eclipses using equipment readily available to the amateur astronomer. The first section, 'Getting Started', presupposes little knowledge of photography or astronomy and concentrates on what can be done with minimal equipment. For example, an ordinary 35 mm camera on a tripod, aimed at the sky on a starry night, will photograph more stars than the unaided eye can see and will bring out an awesome variety of colours. Add a telephoto lens, a pair of binoculars, or a small telescope, and you have all that is needed to photograph an eclipse or the main surface features of the moon. The two subsequent sections, 'Advanced Techniques' and 'Equipment and Materials' cover the use of cameras in conjunction with telescopes and constitute a thorough handbook, including technical imformation on optical systems, film characteristics, and processing techniques. Throughout, the emphasis is on current practice. This book will become the standard handbook for amateur astronomers who want to take pictures of the stars and will also appeal to photography enthusiasts who know relatively little about astronomy but are intrigued by spectacular pictures.
