  4. £45 posted UK. This is a mint, pre-publication hardback copy with an inscription by the Author. This is volume is a massive tour de force, some 665 pages, profusely illustrated throughout. It covers the history of observational astronomy and perhaps more importantly the pioneer astronomers themselves. Whilst the chapters (all 41 of them) are laid out in chronological sequence for good reason, the sections can equally be read as standalone mini-biographies. The list includes some names that are familiar, from Galileo through to the Herschels, Charles Messier, Friedrich Bessel, Thomas Webb, John Dobson, democratiser of sidewalk astronomy in the 1960’s, and famously, the late Patrick Moore. There are many others who might not be so well known such as Clyde Tombaugh, the discoverer of Pluto. Will Hay, better known as a British comedy film actor of the 1930’s and 1940’s. George Alcock, comet and nova discoverer; and David Levy, another of the great comet hunters. All did their finest work as amateurs, all totally dedicated to the pursuit of their hobby.
