The graphic telescope is a type of camera lucida that has the power of a telescope. It was invented by Cornelius Varley in 1809.[1] It can be used to draw broad landscapes.
Graphic telescopes allow the size of the projected image to be adjusted.[2] They can be used separately, or with a portable table to reduce vibrations.[1][3] They may also be mounted in a vehicle.[4]
