This is a guide to the use of the most popular type of telescope in the world, the 20-cm (8-in) Schmidt-Cassegrain telescope. This compact instrument revolutionized amateur astronomy and astro-photography, and more than ten thousand are purchased each year. Peter Manly, a devotee and keen user of the Schmidt-Cassegrain, takes the telescope owner through all aspects of using the telescope in easy stages. It starts with techniques for viewing the Moon, then takes the observer through our planetary system, and on to the deep sky, where nebulae and galaxies are treated extensively. There are interesting projects to try, such as observing the nearest star and chasing eclipses. A full range of telescope accessories and detectors is described together with advice on their use. The 40-page appendix is packed with hard-to-find practical information, arranged in ten separate sections. Peter Manly has written this book to help owners of this telescope design get the maximum enjoyment from observing. But this is not a dry instruction manual. 'It lists all the blunders and mistakes I've made with my telescope in the hope that others can avoid those pitfalls,' he says.

Catadioptric telescopes (CATs), such as the Schmidt Cassegrains, are increasingly popular with today’s amateur astronomers and are capable of showing even the novice observer thousands of beautiful deep space wonders. Modern CATs, though, have become increasingly reliant on computers. This allows them to automatically point to and track celestial objects, making astronomy more accessible to more people than ever before. Unfortunately, because of the high-tech nature of these telescopes, selecting one and learning how to use it is often a difficult experience for stargazers both old and new. That’s where Choosing and Using the New CAT comes in. This book guides even the most greenhorn astronomer past the pitfalls encountered on the path to enjoying the beauties and mysteries of the universe. Here you will learn not just which telescope is right for you but how to set up, operate, and maintain the most complex and electronics-laden CAT. There are plenty of tips for keeping the new CAT happy and working correctly, and there is even guidance on advanced applications, such as hooking computers to CATs and using these telescopes to take gorgeous pictures of planets and deep space objects. This book gives readers the benefit of the author’s thirty-five years experience using and enjoying catadioptric telescopes and solving the problems that inevitably crop up. If you dream of owning a telescope or are frustrated by the telescope you already own, this is the book for you!

This book demonstrates how progress in radio astronomy is intimately linked to the development of reflector antennas of increasing size and precision. The authors describe the design and construction of major radio telescopes as those in Dwingeloo, Jodrell Bank, Parkes, Effelsberg and Green Bank since 1950 up to the present as well as millimeter wavelength telescopes as the 30m MRT of IRAM in Spain, the 50m LMT in Mexico and the ALMA submillimeter instrument. The advances in methods of structural design and coping with environmental influences (wind, temperature, gravity) as well as application of new materials are explained in a non-mathematical, descriptive and graphical way along with the story of the telescopes. Emphasis is placed on the interplay between astronomical and electromagnetic requirements and structural, mechanical and control solutions. A chapter on management aspects of large telescope projects closes the book. The authors address a readership with interest in the progress of engineering solutions applied to the development of radio telescope reflectors and ground station antennas for satellite communication and space research. The book will also be of interest to historians of science and engineering with an inclination to astronomy.
