The Six-Inch Lunar Atlas A Pocket Field Guide

From the reviews:

“This volume is designed as an easy reference companion for the amateur telescopic observer who does not want the inconvenience of using large-scale (and expensive) lunar atlases in dark and damp conditions. It provides finder charts for some sixty popular lunar formations, as well as a more detailed photographic chart for each of those features alongside a short descriptive text. … it is engagingly written by an observer who combines experience of telescopic observation with an infectious enthusiasm for his subject.” (Bill Leatherbarrow, The Observatory, Vol. 130 (1214), June, 2010)

“It will be of use to the ‘beginning or casual observer of the Moon… anyone who wishes to locate the major features on the Moon and to acquire a little knowledge about these formations’. Don Spain is a member of the Louisville Astronomical Society whose first view of the Moon through a telescope in 1958 prompted, in his words, a ‘lifelong love affair with Selene’. The purpose of the atlas is to provide ‘an easily accessible guide for use at the telescope’.” (Nigel Longshaw, Journal of the British Astronomical Association, Vol. 120 (1), 2010)
