JPEG file comment | Clockwork drive designed by the Rev. Sheepshank for refracting telescope of 5.9-inch aperture by Dollond mounted on English type equatorial mounting
Part of: Refracting telescope with 5.9-inch aperture lens by Charles Tully, brass tube and English type equatorial mounting by George Dollond and clockwork drive. Made for Captain W.H.Smyth in 1828, who observed from Bedford and gave the telescope to Dr John Lee of Hartwell House near Stone, Aylesbury. Sold by Lee's executors to Royal Observatory, Greenwich for use in 1874 transit of Venus. Used at the Hong Kong Observatory from 1888 until 1914 when it was returned to Greenwich. SCM - Astronomy Admiral Smyth used this telescope to make his observations for his book, 'A Cycle of Celestial Objects' published in 1844 which was famous throughtout the 19th century. The book was the first guide to the night sky written for a non-specialist and has been much copied since. The instrument incorporates the earliest known clock drive on an English telescope. |
