Brass telescope extendable to a length of 43.5 cm.
A telescope is, like binoculars, an optical instrument to view things well from a distance. Telescopes are monoculars, they have one eyepiece through which you have to look with one eye.
This telescope has been donated to the foundation by Mr. R. Ketting and comes from the legacy of his family from father’s side.
