Antique Astronomical refractor on Equatorial Mount and hardwood tripod. Facsimile of original order invoice dated 1827&1829.
Signed Tulley & Sons Islington on the brass barrel. Aperture 3&3/4-inches Focal Length 60-inches In excellent condition. Brass barrel fitted with Tulley's field illuminator.Aplanatic achromatic objective made by Chas Tulley. Telescope made for John Wrottesley, who in 1842 became the second Baron Wrottesley of Wrottesley Hall Staffordshire. Telescope unscrews into two halves and fits into a mahogany box with carrying handles. The case lock and key are both original. The eyepieces and RAS accessories are mid to late C19th, and are all in full working order as is the telescope. The tube has telescopic steady rods, worm & wheel dog-clutched slow motions and setting circles. Charles (Chas) Tulley began his telescope making business in Islington in the mid 1780's. He was joined by his sons in the early 1820's and died in 1830. At the time this Telescope was made there were very few Equatorially mounted. I have ray-traced the object glass and it is unique to a new bending by Tulley and equal to a contemporary Fraunhofer. The hardwood tripod is reproduction. There's only one other Tulley like this anywhere & it's in the British Science Museum. It will be tracked and fully insured.
The black lacquer Telescope alongside is a c1860 Wray 4 foot achromatic. The item "Astronomical Telescope Tulley & Sons" is in sale since Tuesday, May 1, 2018.
