Description
A brass refracting telescope with celestial and terrestrial drawtubes, the F15 front objective Fraunhofer-type lens with an aperture of 11.5 cm, the focal length of the main barrel 165 cm, the length of the first focusing drawtube 48 cm, the second tube 22 cm, the spotting scope on top 26cm.
Narrative
The telescope was manufactured in France by A. Bardou & Sons of Paris and retailed by A. Chevalier. Its hardwood storage box and other eyepieces is part of the accession.

Hon. James Dunsmuir used this telescope on his yacht. The usefulness of such a large telescope on a private watercraft would normally be questionable due to the continuous movement of small boats. But at 218 feet in length, TSSY Dolaura was reasonably stable. It is likely that Mr. Dunsmuir and his friends used it to spot locations with birds and game before setting out for those places in motor launches or canoes.
