access and a chance to talk with owners of equipment about what
advantages and disadvantages there are to different types of small
telescopes. The Observatory is located in Observatory Park in SE

include So. University (exit 205 south I-25) and E. Evans Avenues.
Chamberlin Observatory, completed in
1894 is unique among Denver landmarks. DU's first astronomy
professor, Professor Herbert Howe, designed it after Carleton College
Goodsell Observatory in Northfield Minnesota. The original
construction drawings by noted Denver architect, Robert Roeschlaub,
are held in the University archives collection, Penrose Library on
the DU campus.
The dome houses a 20 inch aperture
Clark-Saegmuller refractor, which saw first light in July 1894, and
is still "functional". Regular classes and public viewing
still occur. The original description of Chamberlin Observatory and
its large refractor appear in an article by Prof. Herbert A. Howe
that appears in the 1894 Astronomy & Astrophysics (a precursor to
the Astrophysical Journal), volume 8, page 709ff. Limited
edition histories of the observatory are available [click here].
We honor the past and strive to create hope for the future with every
student that peers through the telescope's eyepiece.
