A History of the Telescope...in pictures
Those of us interested in maritime history, the development of science and technology or astronomy, might like to take a look at this Guardian slideshow.
The commentary, based upon his new book The Telescope: A Short History, is provided by Richard Dunn, Curator of Navigation History at the National Maritime Museum and an Associate Tutor in the Department of Museum Studies.
He's also my cousin-in-law, but that's by-the-by. ;)
