Urban Astronomy: Stargazing from Towns and Suburbs

These days, skywatchers don't have to live close to a city or town center to suffer from the effects of light pollution. Urban Astronomy demonstrates how to make the best of poor conditions. Although the unaided eye may be able to pick out only a few hundred stars, binoculars or a small telescope will reveal many more, and advanced aids - like the special filters that let through light from distant nebulae while blocking out wavelengths from streetlights - can give you good views of every type of major astronomical object.
