With the advent of CCDs and webcams, the focus of amateur astronomy has to some extent shifted from science to art. Visual work in astronomy has a rich history. Today, imaging is now more prominent. However there is still much for the visual amateur astronomer to do, and visual work is still a valid component of amateur astronomy. Paul Abel has been addressing this issue by promoting visual astronomy wherever possible – at talks to astronomical societies, in articles for popular science magazines, and on BBC TV’s The Sky at Night. Visual Lunar and Planetary Astronomy is a comprehensive modern treatment of visual lunar and planetary astronomy, showing that even in the age of space telescopes and interplanetary probes it is still possible to contribute scientifically with no more than a moderately-priced commercially made astronomical telescope. It is believed that imaging and photography is somehow more objective and more accurate than the eye, and this has led to a peculiar “crisis of faith” in the human visual system and its amazing processing power. But by analyzing observations from the past, we can see how accurate visual astronomy really is! Measuring the rotational period of Mars and making accurate lunar charts for American astronauts were all done by eye. The book includes sections on how the human visual system works, how to view an object through an eyepiece, and how to record observations and keep a scientific notebook. The book also looks at how to make an astronomical, rather than an artistic, drawing. Finally, everything here will also be of interest to those imagers who wish to make their images more scientifically applicable by combining the methods and practices of visual astronomy with imaging.

Physics and Astronomy of the Moon focuses on the application of principles of physics in the study of the moon, including perturbations, equations, light scattering, and photometry. The selection first offers information on the motion of the moon in space and libration of the moon. Topics include Hill's equations of motion, non-solar perturbations, improved lunar ephemeris, optical and physical libration of the moon, and adjustment of heliometric observations of the moon's libration. The text then elaborates on the dynamics of the earth-moon system, photometry of the moon, and polarization of moonlight. The publication explains lunar eclipses and the topography of the moon. Discussions focus on the photometric model of eclipses, brightness of the solar elementary ring, effects of light scattering, photometry of lunar eclipses, and determination of altitudes on the moon. The text then evaluates the interpretation of lunar craters, luminescence of the lunar surface, and the origin and history of the moon. The selection is a dependable reference for physicists and astronomers interested in the application of principles of physics in the study of the moon.

For many centuries observers of the night sky interpreted the moving planets and the surrounding starry realms in terms of concentric crystalline spheres, in the center of which hung the Earth -- the hub of creation. But with the discoveries of Galileo, Copernicus, Kepler, and Newton, astronomers were suddenly struck by a momentous truth: the solar system was neither small nor intimate, but extended an unfathomable distance toward countless even more distant stars. The endless possibilities of these astounding developments fired scientists'' imaginations, leading both to further discoveries and to flights of fancy. While newly discovered facts are important and interesting, the quaint curiosities and spectral "ghosts" that led scientists astray have a fascination of their own. This is the subject of astronomer Richard Baum in this elegant narrative about the mysteries and wonders of celestial exploration. The fabled "mountains of Venus," a "city in the moon," ghostly rings around Uranus and Neptune, bright inexplicable objects seen near the sun, and the truth behind Coleridge''s "Star dogged Moon" in his famous poem about the Ancient Mariner -- these are just some of the intriguing twists and turns that astronomers took while investigating our starry neighbors. Baum vividly conveys the romance of astronomy at a time when the vistas of outer space were a new frontier and astronomers, guided only by imagination and analogy, set forth on uncharted seas and were haunted for a lifetime by marvels both seen and imagined.
