This is the first non-technical book on spectroscopy written specifically for practical amateur astronomers. It includes all the science necessary for a qualitative understanding of stellar spectra, but avoids a mathematical treatment which would alienate many of its intended readers. Any amateur astronomer who carries out observational spectroscopy and who wants a non-technical account of the physical processes which determine the intensity and profile morphology of lines in stellar spectra will find this is the only book written specially for them. It is an ideal companion to existing books on observational amateur astronomical spectroscopy.

George Forbes' 'History of Astronomy' offers a comprehensive look at the evolution of astronomy from primitive times to the early 1900s. With a balanced approach, Forbes explores the contributions of various cultures and peoples throughout history, from the Chinese and Chaldeans to Copernicus and Newton. The book covers topics such as the discovery of the true solar system, the invention of precision instruments, and the study of the sun, moon, planets, comets, meteors, stars, and nebulae. While providing detailed references, this book is also approachable and engaging, making it an excellent resource for anyone interested in the history of astronomy.
