Sažetak
Recently, the double solar telescope at Hvar Observatory was equipped with the fourth generation of acquisition hardware and software. It provides a valuable tool to study rapid changes of chromospheric and photospheric features in great detail. The telescope consists of two Carl Zeiss refractors (photosphere d=217mm, chromosphere d=130mm) mounted as one unit on a German parallax mounting. Using a field of view of about 8 arcmin, it has the task to produce high resolution images of active regions on the Sun. New Pullnix TM-4200GE MPix 12bit CCD cameras allow time series with a cadence up to 1 image per second.
