This non-achromatic telescope has four draw tubes made of vellum and decorated with gold-tooled motifs. Unusually, it has a tortoiseshell barrel inlaid with silver, and ivory and silver fittings, including a sliding objective and eyepiece lens covers. Stop lines on the draw tubes indicate the optimum working length of the telescope.

It is also interesting to note that the aperture of the objective lens cover is much smaller than the objective lens. It was easier at this time to make a larger lens of good quality and then to stop this down to the size required.
