400 years of the telescope
The collection 400 years of the telescope is a digital representation of a collection of almost 100 celestial maps and prints from the 17th through the 20th centuries. The annotated images (accessible by clicking on an image and next 'Full view of record') offer a varied overview of the development and highlights of 400 years of celestial cartography. This collection deals with two important astronomical milestones. First, in 2008 it was remembered that four centuries ago the telescope was invented in the Netherlands. Second, 2009 was the International Year of Astronomy.
