View of a "barn door tracker" mounted on a camera in the U.S. Laboratory during Expedition Six

ISS006-E-28887 (15 February 2003) --- This view features a �barn door tracker� device assembled by astronaut Donald R. Pettit, Expedition 6 NASA ISS science officer, while onboard the International Space Station (ISS). The device is based on the fine gimbal movements in the IMAX camera mount for the Destiny laboratory window. A drill turns a screw, which moves the camera and its spotting scope.
