The telescope shown against the blue curtain was also a 120 mm refractor, supplied with adapters to allow the instrument to be used both visually and photographically. We shipped it to the client in New York State in 2008.
The brass telescope that we offer as our standard item nowadays has an anastigmat doublet lens with a clear aperture of 127 mm (5 inches) and a focal length of 1500 mm. There are more details of this superb objective in the Starfinders and Eyepieces section of this website.
All of our telescopes, mounts and tripods are hand-made and are to a specification that is agreed by the client, so no two customers ever have exactly the same items, but we can give an indication of prices as follows:
A polished brass telescope with a brass finder: from £7000.
The price of the telescope would largely depend upon the client’s choice of objective lens. This is because the prices of objective lenses vary widely, depending upon the manufacturer, the lens diameter and focal length and whether the lens is available as an ‘off-the-shelf’ item or has to be specially made. The size and focal length of the lens will also determine the size, and hence cost, of the body of the telescope.
