Dollond Refracting Telescope

Description
This telescope has a brass pillar-and-tripod base, a 38-inch long wooden tube with brass fittings, a sliding rod for holding the telescope at a particular elevation, an achromatic objective of 2 inches aperture, four eyepieces, and a wooden box with a hinged lid. The brass ferrule at the eye end of the tube is marked “DOLLOND LONDON.”
The Dollond family began in business as opticians in London in 1750. George Dollond took responsibility for the firm around 1820 and shortened the signature to Dollond.
