Scientific paper
The concept of a new, faster camera for the CES originated in 1981, when it was pointed out that because of the narrow wavelength band covered at one time by the CES, the required correction for chromatic dispersion would be rather small. A dioptrie design was worked out at ESO and the optics were manufactured by Carl Zeiss, FRG. F. Maaswinkel tested the optical quality in Garehing and installed the camera at La Silla in November 1985. At the same time a new CCO Camera was installed at the CES. It mounts a double density RCA CCO (ESO CCO * 8, 640 x 1,024 pixels, 15 ~lm square). The characteristics of the camera, of the CCO and the first astronomical results are discussed below. At comparable resolution, a gain of at least 2 magnitudes is achieved with respect to the Long Camera with the reticon detector.
