Abstract: A CCD camera system has been constructed and is in regular use at the Yunnan Observatory. A Texas Instruments-Japan 1024 $MUL 1024 CCD is employed. The TI-Japan CCD is a virtual-phase with high quantum efficiency, 8 electrons rms readout noise, and excellent charge-transfer properties under low-level light. The CCD controller is designed to operate with multi-functions, the pixels of CCD can be binned into any format. The dewar is cooled by a three stage thermoelectronic device. !8
