The strong and effective links between amateur and professional astronomers were brought into prominence at Colloquium 98 of the International Astronomical Union. Amateur observations of such objects as comets, variable stars and novae serve to complement work done with expensive instrumentation by professionals. They fill gaps left by big science and often contribute significantly to astronomical knowledge. The book covers: - historical contributions by amateurs, - observational methods, problems and instrumentation, - results of amateur observations, - popularization. Overall, an exciting and enthusiastic account of stargazing, the hobby that can turn into science.
