Hartung-Boothroyd Observatory
The primary 0.6m mirror was constructed from a Pyrex 1/8-scale test pouring as part of technology development for the Palomar Observatory 200-inch telescope. The mirror was polished and mounted in a lightweight tube in the late 1930s under Boothroyd's direction, but World War II deferred its planned use in a high-altitude observatory. This facility, together with an equatorial fork mount to hold the previously completed telescope, was completed in 1974.
