James Lick telescope, Refracting telescope at Mount Hamilton Observatory, California.
The Great Lick Refractor contains a 91-centimeter glass lens housed within a dome structure at an elevation of 1,283 meters above sea level.
Constructed in 1888, this telescope remained the largest refracting instrument in the world until the Yerkes Observatory built their 40-inch refractor in 1897.
The University of California operates this scientific instrument, which continues to contribute to astronomical research and offers public viewing sessions.
The telescope features a hydraulic system that controls the movable floor, allowing adjustments of over 5 meters to accommodate different viewing positions.
The remains of James Lick, who funded the observatory with $700,000 in 1876, rest beneath the marble floor of the telescope's observing room.
