Retired at the Griffith Park Planetarium. My 4 visits to this observatory span almost 70 years (1959, 1969, 2021 and last week) and the planterium only on the first and last visits. This instrument came into use after the one and disuse before the other. It looks quite different from what I recall of those used at the Morrison (San Francisco), College of San Mateo, and Hayden (NYC - although I don’t know if was called the Hayden in 1956), spheres studded with lenses for each major star. October, 2025. Cross-view stereophoto.
