Description
Diagram of a reflecting telescope constructed at Kiel, Germany, mounted on a hanging framework, with a cabin and staircases.
The telescope design was inspired by William Herschel’s instruments, consisting of an octagonal tube, 26 feet in length, to receive a speculum mirror of 19-20 inches diameter. Elements of the mount design were taken from Dutch windmills.
Plate 5, illustrating the paper ‘Description of the mechanism of a reflecting telescope twenty six feet in length, constructed near Kiel, in Holstein, by Professor Schrader…’, The Philosophical Magazine…[edited] by Alexander Tilloch, v.1, (1798) pp.113-118.
Inscribed above: ‘Philosophical Mag. Pl.V’. Inscribed lower right: ‘Engraved by Lowry’.
Johann Gottlieb Friedrich Schrader (1763-1833), German physicist. Schrader obtained telescope mirrors from William Herschel, and went on to improve mirror manufacture, and construct instruments at Lilienthal and Kiel.
Wilson Lowry (1762-1824), British engraver and geologist, was elected a Fellow of the Royal Society in 1812.
