Optical Telescopes Part I

| May 18, 2012 | 1 Comment

The beginning of modern astronomy is often linked to Galileo building his first telescope in 1609 — roughly 400 years ago! While he was not the first person to use a telescope, Galileo made many fascinating discoveries, ultimately revealing that the Earth orbits the sun. This video showcases the Zenith Telescope, built by Troughton & Simms in London, England circa 1872. Surveyors used this telescope to mark the boundary between Canada and the United States along the 49th parallel in western Canada.
