Astrophotography for the Amateur

Description

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.
