Carl Zeiss lenses are some of the finest in the world, and have been since the originals. Finding a telescope in this condition, with these optics, that still works, is quite a miracle. Galileo would be proud!



  • Fact 1: Refracting telescopes like this one were used in the 19th and early 20th centuries and use lenses and prisms, rather than mirrors, to magnify images.
  • Fact 2: The first modern, functioning telescope was developed by Hans Lippershey in 1608 and made famous by Galileo's astronomical studies.
  • Fact 3: Carl Zeiss' work on large-aperture lenses led to a boom in commercially available microscopes, telescopes, and camera optics in the late 19th century.
  • Fact 4: The largest single optical telescope in the world is the Gran Telescopio Canarias in Spain, with a massive 10.4 meter reflecting lens.
  • Fact 5: Zeiss optics are still popular, and are found in everything from eyeglasses to submarine periscopes to laser guidance systems.
