Great Refractor Potsdam

One of the most striking features of the science park "Albert Einstein" on Telegrafenberg Hill in Potsdam is the "Great Refractor" - the world´s fourth largest refracting telescope, which was completed in 1899. This telescope bears tremendous witness to the optical precision manufacturing and early astrophysical science taking place at the turn of the 19th/20th century.
The Leibniz Institute for Astrophysics (AIP) regularly provides public observation programmes with explanations about the telescope. Dates are posted on the website of AIP.
