The People's Observatory (shown in photograph) of The Buhl Planetarium and Institute of Popular Science / Buhl Science Center:
10-inch Siderostat-type Refractor Telescope - 1941 November 19 to 1991 August 31
Henry Buhl, Jr. Planetarium and Observatory at The Carnegie Science Center:
16-inch Meade LX200 Schmidt-Cassegrain Reflector Telescope - 1991 October 5 to Present
With the beginning of 2016, it is well into the 75th year of operation of Pittsburgh's Buhl Planetarium Observatory. The 75th anniversary of the Buhl Planetarium Observatory will be on November 19. This photograph, from the late 1970s, shows former Buhl Planetarium Director Paul Oles looking through the historic 10-inch Siderostat-type Refractor Telescope. When observing the Sun, the solar image would be projected from the telescope onto a large projection screen (not shown in this photograph).
