Recently, the double solar telescope at Hvar Observatory was equipped with the fourth generation of acquisition hardware and software. It provides a valuable instru- ment 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 7 and 11 arcmin, it aims to produce high-resolution high-cadence imaging of active regions on the Sun. New Pulnix TM-4200GE 12-bit CCD cameras allow to obtain time series with a cadence up to 30 images per minute.
