摘要:
The results of planetary observations performed with a new CCD detector are presented. The available firmware for collecting a great number of electronic images and the high quantum efficiency of the employed CCD make it possible to observe objects the visibility of which is limited by the short duration of astronomical phenomena. Among such tasks are, for instance, the taking of a large number of images of Mercury by the short exposure method. With a high quantum efficiency of the light detector, short exposure makes it possible to appreciably reduce the blurring of astronomical images caused by the atmospheric instability. This study was performed at the Abastumani Astrophysical Observatory of the Republic of Georgia early in November 2001.
