The Hatfield Lunar Atlas : Digitally Re Mastered Edition The Hatfield Lunar Atlas has become an amateur lunar observers bible since it was first published in 1968.A major update of the atlas was made in 1998 using the same wonderful photographs that Commander Henry Hatfield made with his purpose built 12 inch (300 mm) telescope but bringing the lunar nomenclature up to date and changing the units from Imperial to S.I. metric.However with modern telescope optics digital imaging equipment and computer enhancement new pictures can easily surpass what was achieved with Henry Hatfields 12 inch telescope and a film camera. This limits the usefulness of the original atlas to visual observing or imaging with rather small amateur telescopes.The new digitally re mastered edition vastly improves the clarity and definition of the original photographs significantly beyond the resolution limits of the photographic grains present in earlier atlas versions while preserving the layout and style of the original publications. This has been achieved by merging computer visualized Earth based views of the lunar surface derived from NASAs Lunar Reconnaissance Orbiter data with scanned copies of Commander Hatfields photographic plates using the authors own software.The result is a The Hatfield Lunar Atlas for twenty first century amateur telescopes.
