Denver Astronomical Society

Beneath the distinctive and imposing silvery dome of Chamberlin Observatory lies the beautiful Clark-Saegmuller refractor; a 26-foot-long telescope made from steel, cast iron and brass, which carefully holds within its grasp an exquisitely constructed Alvan Clark & Sons 20-inch doublet lens to view the heavens. The immense telescope assembly is precisely balanced upon a George Saegmuller German Equatorial mount with a backbone of stability achieved with an imposing 4 ½ ton cast iron pillar supported atop a 25-foot tall, 320-ton foundation of red sandstone blocks.

Listed on the National Register of Historic places and currently owned and maintained by the University of Denver, Chamberlin Observatory has been home to the Denver Astronomical Society since 1949. Today Chamberlin Observatory serves as an educational facility for students and the public, inspiring the next generation of astronomers.

The current digital setting circles on the Clark telescope are over 30 years old. New encoding systems are now available that are much faster and more accurate while also making it easier to operate the telescope. The funds raised here will be used to replace the encoder system of the Clark telescope enabling it to operate over 300 times faster and at least 20% more accurately.
