Night telescope
This telescope has a leather-covered barrel and a single brass draw tube. The brass fittings include an objective lens cap and a sliding eyepiece cover. It has a large non-achromatic objective lens to allow as much light as possible to enter the telescope. The telescope doesn’t have extra lenses to correct the inversion of the image created by the objective lens, since the more lenses a telescope has, the greater the loss of light. The production of inverted images is typical of night telescopes.
The maker's name 'Worthington / London' is engraved on both ends of the draw tube. This is Nathaniel Worthington who is known to have been working at 196 Piccadilly from 1835 to 1851.
