Scientific paper

The design and fabrication of an intensified CCD camera made for the purposes of guiding telescopes and of searching fields containing faint stars are described. Special consideration is given to the camera's three working modes: (1) direct exploitation of the video signal sent to the TV monitor, (2) use of an 'averaging filter', which improves the signal to noise ratio, and (3) the 'integration' by the CCD itself. Tests made on an 1.52 telescope confirm the capability of this camera to replace the intensified TV tube cameras. A design diagram of the sensor is presented together with a block diagram of the camera's electronics.
