Mt. Cuba Astronomical Observatory

The aerial photo shows the observatory as it appeared shortly after its construction in the locale of Mt. Cuba, Delaware in 1964.  It is located 14 miles from the University of Delaware campus in northern Delaware near Hoopes Reservoir (visible at top left of the photo).  The dome houses a 24-inch diameter reflecting telescope, which is the main research instrument.

In 1972 a wing was extended from the facing wall of the central pentagon and dedicated to the observatory's educational programs. This educational wing contains a second dome, housing a 4-inch refracting telescope, a small planetarium, and a classroom used for public lectures and as a meeting room for the Delaware Astronomical Society.
