Preface

This book makes extensive use of images from the Digitized Sky Survey (DSS) and the author wishes to thank Lynn Kozloski, Space Telescope Science Institute, Scott Kardel, California Institute of Technology, and Sue Tritton, Royal Observatory Edinburgh, for their permission to use images originally obtained by the Oschin Schmidt Telescope of Palomar Observatory and the United Kingdom Schmidt Telescope of the Anglo-Australian Observatory in the catalogue portion of this book.

We extend our appreciation and thanks to Andreas Maurer and the Antique Telescope Society for permission to use material from their publication A Compendium of All Known William Herschel Telescopes in the chapter entitled ‘The telescope maker’. Mr Maurer also graciously provided the photograph of the 10-foot telescope built by William Herschel and presented to Göttingen University, as well as the photograph of the replica of the 25-foot Spanish telescope.
