Four hundred years ago, on 25 September 1608, the lens maker Hans Lipperhey from Middelburg in the Netherlands traveled to The Hague to apply for a patent regarding his invention of the "spyglass". The Commander in Chief of the Dutch armed forces, Prince Maurice of Nassau, was quite impressed. However, since the instrument could be easily copied, Lipperhey was not granted the patent. Nevertheless, within a year Galileo Galilei aimed a telescope that he had built based on the principals of Lipperhey's device on the skies, forever changing the way astronomy was done.
To celebrate the invention of the telescope and the resulting developments, Leiden Observatory, in cooperation with ESTEC, organized an international meeting on "400 Years of Astronomical Telescopes". The meeting took place from 29 September - 2 October 2008 at the ESTEC conference centre. This book presents the highlights of this meeting under the following categories: History of Optical Telescopes, History of Non-Optical Telescopes, Miscellaneous Aspects and Projects, Fundamental Telescope Technologies, Political and Sociological Aspects, Perspectives for Future Telescopes.
The topical reviews have been written by internationally recognized leaders of the field. This book is intended as a first reference to many technical, historical and social aspects concerning astronomical telescopes. It is equally well suited to professional astronomers as to the interested public.
This book covers beginning back yard astronomy with binoculars and telescopes. It also includes easy to follow polar alignment and star charts.

This book comprises a fascinating collection of contributions on the Merz telescopes in Italy that collectively offer the first survey on historical large refracting telescopes in the country, drawing on original documents and photographs. It opens with a general introduction on the importance of Merz telescopes in the history of astronomy and analyses of the local and international contexts in which the telescopes were made. After examination of an example of the interaction between the maker and the astronomer in the construction and maintenance of these refractors, the history of the Merz telescopes at the main Italian observatories in the nineteenth century is described in detail. Expert testimony is also provided on how these telescopes were successfully used until the second half of the twentieth century for research purposes, thus proving their excellent optical qualities.
