Located inside the Advanced Technology Center, the Clark Planetarium is a large room with 66 seats under a huge dome projection screen. The key piece of equipment in the planetarium is the Digistar II Projection System. Digistar II is the only computer graphics planetarium projection system in the world. The Clark Planetarium is one of only 50 planetariums in the world that utilizes a Digistar projector. A computer automation system controls all of the devices in the planetarium making each program a multimedia experience of sight and sound.
Audience participation is an important part of planetarium programs.
Wired to each seat are three push buttons that allow audience members to respond to questions or to actually take control of the show. Aristech Pendulum Shawnee State University is indebted to the Aristech Chemical Company for the pendulum that graces the atrium of the Advanced Technology Center.
