Description: | DEXTRA ME VIBRAT
Dollond London / Achromatic Night
VI
This achromatic telescope has a leather-covered barrel and a single silvered-brass draw tube. The other fittings are also silvered brass and include a pivoted eyepiece cover, an objective lens cap and a sliding sunshade. Unusually for a telescope of this date, there is no mechanical stop on the draw tube, which may be pulled freely out of the barrel. There is, however, a stop line engraved on the draw tube to indicate the optimum working length of the telescope.
The words 'Achromatic Night' are also engraved on the draw tube, indicating the telescope has been designed for use in poor light conditions. It has a relatively large objective lens to collect as much light as possible when viewing at night.
The telescope is one of a group of telescopes (with NAV1562, NAV1563, NAV1564) that belonged to a T.H. Hand. The maker's name is engraved on the draw tube as ?Dollond London?, as is an emblem of an arm with a sword in its hand above the motto 'Dextra me vibrat' ('Brandished in my right hand').
