1707578947Code 7834 Antique TelescopeBrass telescope with leather-covered handle and two-extension focus, complete with cap and dust cover. English manufacture from the second half of the 19th century. Maximum length 40 cm, 15.7 inches, minimum 16.5 cm, - 6.7 inches, focal diameter 3 cm - 1.2 inches. In good condition, fully functional and complete with custom-made wooden and brass support base. To focus the telescope you need to extend it completely and then slowly shorten the last extension, the smallest one, until the image is in focus.

According to legend, one unspecified day in 1608 the children of Hans Lipperhey, who was an eyeglass maker from Middelburg, were playing with lenses in their father's workshop. When one of the sons placed a concave lens near his eye, holding a convex lens in the other hand, and holding out his arm towards the tip of the bell tower of the cathedral, looked through it, he saw the weathercock that was on the top grow bigger and get closer. . Having immediately shown the phenomenon to his father, he fixed the lenses on a board to make observation easier, thus creating the first rudimentary telescope. Unfortunately for Lipperhey, however, when he presented a patent request for this instrument to the States General, within a few days other Dutch eyeglass makers also claimed the invention.
