Light-pollution is the modern scourge of optical astronomy. An increasing number of observing sites are in danger of being rendered useless due to the glare of city lighting blotting out the night sky. Professional astronomical observatories are located far from cities, but amateur astronomers often do not have this luxury. This book considers the two available strategies open to Astronomers. The first involves campaigning against light pollution by lobbying Authorities and Standards Organisations, and the second involves using the correct instrumentation. The book contains an extensive detailed catalogue of deep-sky and other objects that - despite what one might believe - can be seen from variously light-polluted sites, for practical observers.
