Chris Kitchin is Emeritus Professor of Astronomy at the University of Hertfordshire and has a lifelong interest in astronomical instrumentation, using telescopes of all sizes, studying the rapidly growing number of planets known to orbit other stars, and trying to communicate his own excitement at the recent explosion of discoveries about the universe. When not a hundred light years from Earth (at least in his imagination), Chris enjoys being taken for long country walks by his two border collies.§He is author of a vast number of scientific papers and sixteen books by various publishers, including Springer's Illustrated Dictionary of Practical Astronomy, Solar Observing Techniques, Seeing Stars, A Photo Guide to the Constellations, Exoplanets, Galaxies in Turmoil, and of course the first two editions of Telescopes and Techniques, which sold in excess of 12,000 copies.
