The
Dearborn
Observatory is located on the Northwestern University campus. Housed
inside the dome is an 18.5" Clark Refractor. The orginal lenses,
made in 1861, are still used today although they are now housed inside
a new telescope. The original
telescope now resides at the Adler
Planetarium in Chicago. Alvan
Clark and Sons were the finest lens makers of the 19th century.
Their telescopes are still used by many other University Observatories
around the country, including University of Virginia's McCormick
Observatory and University of Chicago's Yerkes
Observatory. |
