The Doane Observatory - Chicago, IL - Astronomical Observatories on Waymarking.com

The Doane Observatory on the shore of Lake Michigan is affiliated with the Adler Planetarium. It is home to the largest telescope available to the public in the Chicago area.
"The specific design that our current telescope is based on is called Dall-Kirkham. The concave 24-inch mirror is shaped as an ellipse, and the smaller convex secondary mirror is shaped as a part of a sphere. However, one problem with Dall-Kirkham telescopes is that objects at the edges of the view can appear misshapen and distorted. PlaneWave staff created a version of this design called a Corrected Dall-Kirkham, or CDK. There is a set of correcting lenses that is situated in the light path just in front of the eyepiece."
