Astrometric measurements of 18 visual double stars carried out with a CCD are given. The present observations are a test of the propriety of the CCD technique for astrometric observations of visual double stars. The duration of the observations was 75 minutes. The precision of the CCD measurements corresponds to the precision of the photographic method, so that the advantages of CCDs are the great loss of reduction work and the corresponding time savings, including shortening of the observing time.
