This book is aimed at the amateur astronomer who has passed through the first stage of getting acquainted with the sky, and decides to concentrate on a particular object or class of objects and make serious observations. The scope ranges from meteors in the upper atmosphere to exploding stars in distant galaxies, and the front-line observational techniques have become so specialized that no single author could write effectively about them all. "Sky Watcher's Handbook" has been written by a selection of amateur astronomers who are leaders in their particular field. The brief to each contributor was to concentrate on the areas of work where the dedicated amateur can make a useful contribution; the equipment and resources needed; and the observational techniques to be employed. The result is the most up-to-date and comprehensive distillation of collective wisdom available to the amateur astronomer.
