The Kaguya Lunar Atlas

by Motomaro Shirao

In late 2007, the Japanese Space Exploration Agency (JAXA) placed the Kaguya/ Selene spacecraft in orbit around the Moon to probe the Moon’s surface and interior. But unlike previous lunar orbiters, Kaguya carries a high definition television camera (HDTV) sent beyond Earth orbit. Sponsored by the Japanese NHK TV network, the HDTV has amazed both scientists and the public with its magnificent views of the lunar surface. What makes these images so much more engaging than standard vertical view lunar photography is that they are taken looking obliquely along the flight path. Thus, they show the Moon as it would be seen by an astronaut looking through a porthole window while orbiting only 100 km above the lunar surface. This is the view we all would wish to have but are never likely to, except vicariously through the awe-inspiring Kaguya HDTV images. Each page features a HDTV image with a map of the entire Moon on the upper left showing where the image is located. On the upper right is a 100-150 word description. Seeing the Moon is not intended solely for lunar scientists who are striving to work out the mysteries of the Moon’s origin and evolution. Everyone can appreciate the natural beauty and be entranced by the view of the nearby world where humans may one day live.

The Hatfield Lunar Atlas

by Anthony Cook

"The Hatfield Lunar Atlas" has become an amateur lunar observer's 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 This edition is important since the fact is that modern telescope optics, digital imaging equipment and computer enhancement can easily surpass what was achieved with Henry Hatfield's 12-inch telescope and a film camera. This limits the usefulness of the original atlas to visual observing or imaging 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 NASA's Lunar Reconnaissance Orbiter data, with scanned copies of Commander Hatfield's photographic plates, using the author's own software. The results is a "The Hatfield Lunar Atlas" for 21st century amateur telescopes up to and beyond 12-inch aperture.

The Hatfield SCT Lunar Atlas

by Anthony Cook

In 2004, it became obvious that Henry Hatfield’s original atlas wasn’t suitable for all current commercially-made amateur telescopes. Newtonian telescopes and astronomical refractors – for many years the only choice for amateurs – invert the observed image. The standard Hatfield Atlas therefore follows the IAU (International Astronomical Union) convention of having maps (and photographs) with South at the top and West on the left: an inverted image. However, the current ranges of Schmidt-Cassegrain and Maksutov telescopes – that’s most of those manufactured by Meade, Celestron, and many others – don’t invert the observed image but instead reverse it left-for-right. That’s with North at the top and East on the left. Because of the way the human visual system works, it is almost impossible to mentally ‘mirror-image’ a map to compare it with the view through the eyepiece , so even turning an IAU-standard atlas upside-down doesn’t help! This new SCT version of the Atlas solves this problem for observers. Identification of lunar features is made quick and easy. The new, digitally re-mastered second 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 – whilst 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 NASA’s Lunar Reconnaissance Orbiter data, with scanned copies of Commander Hatfield’s photographic plates, using the author’s own software. The result is a The Hatfield SCT Lunar Atlas for 21st century amateur telescopes up to and beyond 12-inch aperture. It contains all the features that made the original so widely used: a combination of an index of all International Astronomical Union named primary lunar features, and twelve chart areas help to locate any named lunar features of interest that can each be examined under typically five different states of illumination. Close ups of interesting features are also included. The new Atlas is supplemented by an introduction to its use, a short description of the digital re-mastering technique, and a completely new section describing lunar observing techniques. At the end of the atlas there is an index of all named features and crater diameters, along with a summary table of the dates and times that the original Hatfield images represent.

The Chang E 1 Topographic Atlas of the Moon

by Chunlai Li

This atlas is based on the lunar global Digital Elevation Models (DEM) of Chang'E-1 (CE-1), and presents CCD stereo image data with digital photogrammetry. The spatial resolution of the DEM in this atlas is 500m, with horizontal accuracy of 192m and vertical accuracy of 120m. Color-shaded relief maps with contour lines are used to show the lunar topographical characteristics. The topographical data gathered by CE-1 can provide fundamental information for the study of lunar topographical, morphological and geological structures, as well as for lunar evolution research.

The Moon s Largest Craters and Basins

by Charles J. Byrne

This most recent book from lunar expert Charles J. Byrne combines the latest comprehensive imagery, topography and gravity data from all three recent Moon missions, Kaguya, Lunar Reconnaissance Orbiter and GRAIL. These major polar-orbit surveys are presented here in compact form for the convenience of amateur and practical astronomers concerned with the Moon. Chosen from the Near and Far Side's large craters and basins over 200 km in diameter, each of the 71 highlighted features is depicted with a two-page presentation of the data that includes false color topographic maps next to the mission images. Additionally, the features are presented in the estimated chronological sequence of their creation, based on a consideration of stratigraphy (overlapping layers from neighboring features) and the relative degradation of surface features. Using this sequence as a way to convey the relative ages of lunar features, the author presents various theories concerning the Moon’s impact and thermal history e.g. the available evidence allows for constraints to be placed on the duration of the Late Heavy Bombardment period. The relationships between impact dynamics and variations in the gravity field of the Moon are also discussed. The new mission data makes possible this renewed conjecture about the history and evolution of the Moon, which is presented here with much worthwhile information for amateurs and professionals alike.
