Our once-a-month first quarter moon
Saturday evening Open House events, weather permitting runs from ~7pm
til ~10pm, weather permitting. Observing with the large telescope is
$1 per person to help offset cost of maintenance, and the astronomy
club brings numerous portable telescopes which are set up in the
park, with free for all viewing. This provides the public great sky
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
Denver, at 2930 East Warren Avenue. Major intersections nearby
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.
