An automatic guiding system of solar Gregory telescopes has been developed in joint cooperation of the Fachhochschule Wiesbaden and the solar observatories at Locarno/Switzerland and on Tenerife. Exact positioning of the solar disc is achieved by means of a two-dimensional intelligent sensor being illuminated by a reduced image of the telescope's primary focus. This allows to precisely fix (i.e. < 1 arcsec) any location on the solar disc. The observer has at his disposal all relevant functions for a comfortable computer control of the telescope. The software has been developed on a PC largely by means of the graphical language LabVIEW, which is also considered for the development of the GREGOR control software.
