Venus and Mercury have always been regarded as difficult targets for amateurs, but advances in commercially-made instruments have brought them within range of only moderately experienced observers. The concept of this book is to present an up-to-date detailed description of the history and geology of the inferior planets, and also to provide the best information about observing and recording them with commercially-available telescopes and cameras.

SketchingtheSkies Suddenly and without warning, a new star appeared in the night sky, and everyone in the community was alarmed. Nobody could remember having seen its like before. Dazzling to look at, this unexpected intruder in the heavenly vault gave off a light that almost rivaled that of the full Moon, drowning out the familiar patterns of stars with its glare. The new star’s steady white light penetrated deep into the sacred cave, illuminating an age-old patchwork of intricately drawn pictographs; some of these depicted terrestrial objects and events, from mundane sketches of bison to vast and sweeping panoramic images of wild galloping horses. Other scenes showed celestial phenomena, such as the phases of the Moon and prominent asterisms, or star patterns. The next morning, accompanied by solemn chanting in which the entire c- munity participated, an elderly shaman entered the sacred cave by the light of a fiery brand and selected a suitable area upon which to depict the new star. Once the artwork was finished, the shaman reappeared at the cave entrance; he held out his arms wide to the slowly brightening morning skies and announced that the pow- ful magic of the new star had been captured and could now be used to ensure the continuing prosperity of his tribe.

In 1609 Galileo first used his telescope to kick start the science of observational astronomy - an event that proved to be of enormous historic, scientific, and cultural importance. Galileo and 400 Years of Telescopic Astronomy will feature the life and achievements of Galileo, around which has pivoted the story of four centuries of telescopic astronomy. The book will detail how astronomy has progressed through four centuries and contain glimpses of future space research and astronomy goals. Uniquely, interwoven with the text will be a range of practical projects for backyard astronomers in which to participate, projects that serve to illustrate many of Galileo's scientific discoveries.

Mars, popularly known as the Red Planet because of its distinct color, is visible with the naked eye and is one of very few planets in the Solar System in which it is possible to see weather phenomena and surface features and thus is a favorite for amateur and practical astronomers. Commercially made telescopes can reveal its dusty surface markings, brilliant polar ice caps, and atmospheric phenomena. Many of Mars's features appear to change shape and intensity with the seasons: its polar caps grow and shrink cyclically, clouds billow above the Martian surface, and sometimes great dust storms obscure vast sections of the planet.The first part of Mars and How to Observe It sets out our current knowledge of Mars as a planet - its orbit, physical characteristics, evolution over time, and current geology. A planet-wide tour of Mars's topography is featured, along with clearly labeled maps and close-up images of a variety of features. The second part of the book explains how amateur and practical astronomers can observe Mars successfully. Many aspects are considered in depth, including preparing to observe, calculating phase and tilt, and making observational sketches and drawings. There are also plenty of details about how best to make high-resolution CCD images. Since Mars changes in its apparent size in the sky according to its position in relation to Earth, it is best observed during its closest approaches. Future apparitions (appearances of the Red Planet) are therefore featured.

This revolutionary new book is written for practical amateur astronomers who not only want to observe, but want to know the details of exactly what they are looking at. The Moon and How to Observe It is a mine of information for all levels of amateur observers, from the beginner to the experienced
