The MAGIC near-infrared and optical CCD cameras of the 1.23 m telescope, both in the Cassegrain focus of the telescope. (a) shows MAGIC near-infrared camera. The MAGIC detector is a 256 256 pixel HgCdTe array, providing a field of view of . The filter wheel of MAGIC allows broad-band imaging. The instrument is only mounted by special request, so it is not usually available. (b) shows optical CCD camera running on the 1.23 m telescope of Calar Alto. The optical CCD camera is based on a 2 k 2 k SITE#2b chip. The green tube is the dewar and the white box is the electronic system associated to the camera. The filter wheel is located in the black flange just on the detector dewar.
