This book covers the "why," "how," and "what" of astronomy under light-polluted skies. It is aimed at urban astronomers and showcases the countless objects - galaxies, nebulae, and star clusters - that can be seen in even in heavily light polluted urban skies. About half of the book is devoted to describing "tours" of the sky, with physical and observational descriptions, at-the-eyepiece drawings, and photographs. There are literally hundreds of spectacular objects to be seen from the average urban site. After dealing with equipment, locations and even urban safety, the author invites the reader to join him on his virtual "walking tours" of the night sky..
