Long regarded as the finest photographic lunar atlas available, The Hatfield Lunar Atlas is a model of accuracy and clarity. This new version updates some of the maps, names and technical data, but uses Commander Henry Hatfield's original - and unexcelled - photographic plates, taken with a purpose-built 30 cm reflector. The Atlas is divided into sixteen sections, each of which is made up of five or more photographic plates together with a map. Each map is based primarily of the facing plate. Where detail is lacking on this primary plate (particularly near the Moon's limb) supplementary detail is provided by one or more of the other plates in a particular section.
