Observatory

The Pohl Observatory at GC hosts a 24-inch Corrected Dall-Kirkham (CDK 24) Astrograph telescope optical tube assembly manufactured by Planewave Instruments with focal ratio of f/6.8. The CDK 24 is designed to have no field curvature, off-axis coma, or astigmatism over a 70mm image. It sits on a Mathis Instruments Fork Mount MI-1000. The entire assembly is installed on the 4th story of Herty Hall atop of an isolated pier in a 16 ft Ash Dome.

GC will open the observatory for public observing at regularly scheduled events and special astronomical events. All observing times are subject to weather conditions. In the event of rain or cloudy skies, the observatory session will be canceled and a presentation will be offered in the Planetarium located in the Natural History Museum (1st Floor of Herty):
