Prismatic telescope
This is an inverting astronomical telescope. The barrel is made of mahogany, while the two draw tubes are brass. The eyepiece tube contains a prism instead of an eyepiece lens. This reflects the light from the objective lens through an eyepiece on the side of the tube.
The telescope also still has its original red leather case, as well as the brass cap for the objective lens. The maker's name is inscribed on the smaller draw tube as ‘Dudley Adams. Invt. / Charing Cross’.
The telescope is supposed to have belonged to Colonel George Frederick Pascal, who was involved in the Battle of Waterloo in 1815.
