Large A3 size with few pages but essential reading for the newcomer to astro spectroscopy. A modern and profusely illustrated student's textbook covering the whole universe of astronomy. Invaluable to the amateur spectroscopist too. Plenty of spectra from planet Venus to distant quasars with explanations, formulae and associated maths. A profusely illustrated compilation of works by various top British astronomers with much to interest the spectroscopist.
Spectroscopy is in there too.
A definitive work by the experts that has dated little down the years although some of the spectral classifications have been updated Contains a useful section on variable spectra amongst variable stars. Provides a very useful insight and background to current variable star work. Liberally sprinkled with references to solar and stellar spectroscopy and very readable. This perennial work first published in 1910 must now be close to a 20th edition. Contains starcharts to mag 6 covering the whole sky and invaluable to the amateur planning an evening's observation.
