A highlight of the show floor is the collection of antique telescopes, some dating from the early 1700s. These early examples of optics technology are interesting not only from a historical perspective, but from a materials and technology perspective, too. Watch the video of John Grievenkamp, Univ. of Arizona, to get some insights into this great collection of instruments.
