CMT CCD System

During late March and early April 1999 a new CCD camera was fitted to the Carlsberg Meridian Telescope on La Palma. This is a Copenhagen University Observatory custom built camera using a Kodak 2060 x 2048 (KAF-4202 Grade:C1) chip. The chip can be cooled to -65°C by a Peltier cooler and has a pixel size of about 9µm (0.7 arc seconds). Currently, we are cooling the chip to -30°C since this reduces the effect of a charge transfer efficiency problem with the chip. The higher operating temperature does not affect our magnitude limit.
