The refracting achromatic telescope was invented and patented by John Dollond in 1758. Joseph Cappo appears as a Barometer, Thermometer, Chemical and Philosophical Instrument maker in the Ulster Address lists around the 1860s (168 Millfield Rd). On the other hand, Newton & Co.Are also registered, at that time, as Opticians, Mathematical, Philosophical & Astronomical Instrument makers based in Fleet Street, Temple Bar, London. Given the size of the telescope it may have been built as an astronomical device. The telescope has a few small knocks, but they do not detract in any way from the beauty of the piece. The case is made of mahogany.
The telescope is balanced on a brass column, which has a telescopic strut to give rigidity and precision to the viewing. A small desk tripod one of the screw is lost witch you attach the telescope to the tripod. The size when on the tripod is 51cm high.
The telescope is 117cm in length and when wound in its 42cm. The side scope is 25cm in length. The lens size is 7cm in diameter. The tripod is 43cm high. The item "A STUNNING LARGE NEWTON AND CO CIRCA 1870 CASED REFRACTING TELESCOPE" is in sale since Tuesday, July 17, 2018.
