The second/middle photograph is of Buhl Planetarium's first telescope (1939), a 4-inch Zeiss Terrestrial Refractor Telescope used in Buhl's People's Observatory; in 1941 a 10-inch Siderostat-type Refractor Telescope was dedicated. The third photograph, on the right, is of The Buhl Planetarium and Institute of Popular Science.

Friends of the Zeiss is a non-profit organization with the mission to promote Astronomy, Space Science, and other sciences to the general public through Internet web sites, SpaceWatchtower Blog, and SpaceWatchtower 'X' / Twitter News Feed, as well as public observing sessions of special astronomical events and other public educational programs and services regarding Astronomy, Space Science, and other sciences. This organization also promotes the history and preservation of the historic equipment, artifacts, and building of Pittsburgh's original Buhl Planetarium and Institute of Popular Science, including the Zeiss II Planetarium Projector (prior to 2002 dismantling, oldest operable major planetarium projector in the world !) and the fairly unique 10-inch Siderostat-type Refractor Telescope.
