Schematic of one of the four Pan-STARRS gigabit cameras. About a dozen of the 64 OTA devices can be seen through the 56-cm diameter window, which also comprises the final corrector lens in the optical path of the telescope. The eight blue-grey boxes contain the readout electonics for the OTA devices. The overall length of the camera is about 1.5 meters. Image Credit: University of Hawai'i
