Over the weekend, Erica and I visited the Yerkes Obervatory, near Lake Geneva, WI.

Yerkes Observatory, which calls itself “the birthplace of modern astrophysics,”[1], is an astronomical observatory operated by the University of Chicago in Williams Bay, Wisconsin. It was created in 1897 by George Ellery Hale and financed by Charles T. Yerkes. The observatory represented a shift in the thinking of observatories, from mere housing for a telescope and observer, to the modern concept of observation equipment integrated with laboratory space for physics and chemistry. A 102 cm (40 inch) refracting telescope built by the master optician Alvan Clark is located inside. It is the largest refracting telescope used for scientific research (a larger demonstration refractor, the Great Paris Exhibition Telescope of 1900, was exhibited at the Paris Universal Exhibition of 1900). ~Wikipedia

I pieced a few shots together to make this panographic photo (click it to see it bigger):
