SCT and Maksutov telescopes - which of course includes the best-selling models from Meade, Celestron, and other important manufacturers - reverse the visual image left for right. It is extremely difficult to identify lunar features at the eyepiece of one of these instruments using a conventional atlas. The human brain just doesn’t cope well with trying to compare the real thing with a map that is a mirror-image of it. This new SCT version of Hatfield’s famous lunar atlas solves the problem. Photographs and key maps in The Hatfield SCT Lunar Atlas are mirror-images, to show the Moon exactly as it appears through the eyepiece of an SCT or Maksutov telescope. Identification of lunar features is made quick and easy. The Moon’s surface is shown for various sun angles, and there are inset keys that show the effects of optical libration - all mirror-imaged for SCT users. Smaller IAU-standard reference images are included, to make it simple to compare the mirrored SCT photographs and maps with those that appear in other atlases. This edition still uses the superb original photographs taken by Commander Henry Hatfield using his 12-inch reflector. The key maps, on which lunar features can be readily identified, have been reversed and updated, but retain the style and clarity that made the original justly famous

This book tells the story of the Soviet and Russian lunar programme, from its origins to the present-day federal Russian space programme. Brian Harvey describes the techniques devised by the USSR for lunar landing, from the LK lunar module to the LOK lunar orbiter and versions tested in Earth’s orbit. He asks whether these systems would have worked and examines how well they were tested. He concludes that political mismanagement rather than technology prevented the Soviet Union from landing cosmonauts on the moon. The book is well timed for the return to the moon by the United States and the first missions there by China and India.

Harold Hill's book is a unique collection of drawings published for the first time in this form. The illustrations are supplemented by text often taken from observing notes at the telescope. Astronomical drawing still has an important place alongside photography in the same way that photography has not supplanted the artist in the field of botany and ornithology. Indeed, because of movements in the Earth's atmosphere, astronomical images tend to shimmer even under the best possible conditions; drawings constructed by an artist who takes advantage of the fleeting moments of perfect vision are often more detailed than photographs. No one can fail to be impressed by the beauty and artistry of this work and, for the initiated, the accuracy and attention to detail is remarkable.

The face of the Moon we see today has been substantially etched by the effects of meteor impacts. Craters on the Moon are the result of ancient impacts with large meteorites - or small asteroid-like bodies - which produced both primary craters (where the meteorites hit) and secondary craters (where material hurled high above the surface crashed back down). Even some of the vast lunar "seas" - actually basalt plains from ancient volcanic eruptions - may have been the result of impacts that triggered lava outflows. The era of major impacts on the Moon may have passed, but lunar meteorites may well be the cause of what are known as Lunar Transient Phonomena ("LTP" or sometimes "TLP") flashes and puffs of gas or vaporized rock or dust that are observed on the Moon's surface. This book looks at the way the Moon has been shaped by meteorites, proposes lunar meteorites as the most likely cause of most LTPs and describes in practical detail how amateur astronomers can observe impacts on the Moon, past and current. |
