The CCD cameras used by me are briefly described below. $ Santa Barbara Instrument Group ST-6 and ST-8 CCD cameras.
SBIG ST-6 model CCD camera was the first CCD device available to Bulgarian astronomers. It was kindly made available by EAS/ESO support of Astronomy in the Central/Eastern European countries in 1992 thanks to the efforts of Dr. R. West and Dr. M. Tsvetkov. During the period 1993-1996 the CCD ST6 was attached to the Ritchey-Chretien focus of the 2/16 m RCC telescope at the Rozhen NAO of Bulgaria. In 1995 and 1996 successful probe observations with ST-6 mounted instead of the plate holder of the 50/70/172 cm Schmidt telescope were made; the regular observations started in 1998. In the begining of 21-st century ST-6 was replaced by a SBIG ST-8 CCD camera. At the present time ST-6 is used as a detector of the UAGS spectrograph. The CCD camera is still functional except the fact that from time to time long exposures (e.g. 1800 sec) are not read correctly, so the corresponding frames are unuseful. I have some experience with that: after a 30 min of guiding the telescope I found just a noise instead of AGN spectra. Some of the long exposure dark frames were also lost due to the same problem.
