Astronomical Cybersketching

by Peter Grego

This truly unique book has become necessary because of the newest advancements in computer technology. It outlines the techniques involved in "cybersketching", or making observational astronomical sketches and detailed 'scientific' drawings using modern digital equipment, primarily PDAs and tablet PCs. Choosing hardware and software is discussed, followed by the techniques involved in producing finished drawings. Completing and enhancing these drawings at the desktop PC is also covered. No other book to date deals with the subject of digital observational drawing. People are increasingly 'digitizing' their lifestyles, and future amateur astronomers will not have to contend with juggling soggy paper and smudgy pencils at the eyepiece! Those who have seen the techniques pioneered by the author have universally commented the use of handheld PCs with touch sensitive screens is the future of recording visual observations of astronomical subjects.

Galileo and 400 Years of Telescopic Astronomy

by Peter Grego David Mannion

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 and How to Observe It

by Peter Grego

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.
