Troughton & Simms Refracting Telescope

Troughton & Simms Refracting Telescope

<< >>
Usage conditions apply
This brass telescope has a pillar-and-tripod stand, an achromatic objective of 2⅞ inches aperture, an eyepiece, and holders for a telescoping brace (no longer extant). The tube is 45 inches long. The inscription on the faceplate at the eye end reads “TROUGHTON & SIMMS / LONDON.” The firm of Troughton & Simms began trading as such in 1824. It became Troughton & Simms, Ltd., in 1916, and Cooke, Troughton & Simms, Ltd., in 1922.
The University of Alabama at Tuscaloosa built an astronomical observatory in 1843-1844 and probably acquired this telescope at that time. The school did not admit women until the 1890s.
