A brief list of solar telescopes that have been used in the Ondřejov observatory is given. Currently, solar observation is concentrated to the following devices: Chromospheric anf photospheric telescopes of the solar patrol, horizontal spectrograph HSFA2, laboratory spectrograph SLS and the robotic telescope SORT which is still under finishing. We give also a concise list of the Ondřejov solar radiotelescopes. We describe the main technical parameters of the telescopes, properties of the detectors used, organization of observations, data archives and usage of the data in the solar research.
