Paper Abstract

The electrographic camera is one of the most powerful modern detectors having high sensitivity, extend spectral response, high spatial resolution, low background, no threshold, good linearity and large dynamic image. That is precisely because of this, the electrographic cameras with various designs have been developed in the past decades and many exellent astronomical results were obtained by use of them (Chicarini et al. ,1974). In general, the effect of their utilization in astronomical observations not only is to extend the detection limit of a large telescope, but will be to transform every existing telescope of <1. 5-m aperture into one of 5-m.
