GC is proud to present the GC planetarium, where students can view digital simulations of the sky in an immersive 20 ft diameter dome view with guides, labels, and motion. The planetarium also has the ability to display full dome show content. This Digitarium Epsilon projector has all the abilities of a computer vs. the slide projector views of the past.
The planetarium has been in use as part of the GC astronomy labs since Fall semester 2008. It is also been a common part of campus outreach with visits from Kid's University, Boys and Girls club, PRELIMS, GNETS, and SEE programs. Local teacher preparation programs and summer workshops have also had the chance to experience the educational opportunities of this system.
The planetarium has been funded through the Department of Chemistry, Physics and Astronomy, the GC Student Technology Fees Committee, and the generosity of the Grassman Foundation.
GC has installed the 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 of note (usually the first Friday of the month). 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 Georgia College Planetarium located in the Natural History Museum (1st Floor of Herty).
Shows for the public occur once a month during the academic year in conjunction with the public observatory nights (usually the first Friday of the month, weather permitting).
