Greenwich 28-inch refractor, Optical telescope at Royal Observatory Greenwich, England
The Greenwich 28-inch refractor telescope stands inside a spherical onion-shaped dome that extends beyond its supporting tower at the Royal Observatory.
Installed in 1893, the telescope features a mounting from the 1850s designed by Royal Observatory director George Airy with Ransomes and Simms company.
The telescope contributed to astronomical research with over 1300 observations of double stars conducted between 1960 and 1963 at the Royal Observatory.
Visitors can participate in the Great Equatorial Encounter program, which includes presentations about the telescope's mechanisms and astronomical observations.
During World War II, the telescope's objective lens was removed and stored separately to protect it from potential damage during military conflicts.
