Witte Observatory Complex

From the Southeastern Iowa Astronomy Club:

The Witte Observatory Complex will be CLOSED to the Public until april of 2021. With the possibility of over 100 visitors on Public Viewing evenings the Executive Committee decided we cannot operate telescopes, sanitize equipment and/or maintain crowd movement to satisfy current Covid-19 requirements.

The JOHN H. WITTE, JR. OBERVATORY COMPLEX consists of three separate observatory buildings. It is located at 18832 152nd Avenue, Sperry, Iowa in Big Hollow Recreation Area approximately 12 miles north of Burlington, Iowa.

Witte Observatory Building houses a 12-inch aperture refractor manufactured in 1937 by Alvan Clark and Sons. It is doublet achromatic design with a brass tube approximately 15 feet long resting on a German Equatorial mount. Depending on the eyepiece used, it can magnify celestial objects up to nearly 400 times. This telescope is believed to be the largest refractor in Iowa. John H. Witte, Jr gave this telescope to the Burlington School district housed at Apollo School. The Des Moines County Conservation Board owns the telescope and the Southeastern Iowa Astronomy Club members built a building to house the telescope which was completed in 1987.
