EARLY 19TH CENTURY TELESCOPE

A fine single draw telescope with 5.1 centimetre (2 inch) doublet object lens and squared off collar, attributed to Dolland circa 1820; black leather bound, with removable sliding end cap, ray shade and sliding ocular dust cover, this hand held refractor has superb optics with an estimated 20X magnification; a couple of minor knocks but a fine survivor of the era

Most telescopes circa 1800 have an ogee collar and this one is flat and squared off; single draw is nice and tight, as are all of the tolerances; although unsigned, it appears to be of the workmanship of Dolland - length when closed 52.1cm (20 1/2in)
