An exceptional floor standing telescope by the celebrated Dollond firm, the most widely known and well-respected English maker of telescopes and spyglasses of the 18th and 19th centuries. The firm was begun in the mid 1700's by British optical designer John Dollond, who is known for his invention of a number of precision instruments used in astronomy, geodesy, and navigation, including an achromatic lens which used two different types of glass to provide much better color correction than the simple lens objectives that were used to date. For this work, Dollond received the Royal Society's Copley Medal, as well as the council medal of the Great Exhibition of 1851 for his atmospheric recorder that simultaneously measured and recorded on paper tape temperature, atmospheric pressure, wind speed and direction, evaporation, and electrical phenomena.
