At present, two large horizontal solar telescopes with spectrographs, located at the Ondřejov Observatory, are undergoing an important reconstruction. The original designation of these two identical instruments will mostly be preserved. The telescope/spectrograph HSFA1 will continue to be used for the measurement of solar magnetic and velocity fields, while HSFA2 is in the process of rebuilding to a multichannel spectrograph equipped with CCD cameras. The reconstruction of theelectronic control systems is the most important item. The up‐to‐date electronic equipment will enable a remote control of all functions of the instruments, will offer a large amount of automated procedures and should resist to disturbances caused by atmospheric electricity. The whole telescope/spectrograph control system is designed to reduce and simplify the observer's work as much as possible.
