This is a clear and simple introduction to the calculations that form the basis of all astronomical laws and observations. Most elementary astronomy books are purely descriptive, while textbooks of mathematical astronomy assume a considerable knowledge of mathematics. Here the author relies only on simple 'school maths' to help the amateur widen his horizons and interpret his observations.

This work features approximately 150 detailed historic photographs from The Francis Frith Collection with extended captions and full introduction. Suitable for tourists, local historians and general readers.
