dc.description.abstractContext.We measured the angular separations, position angles, $Delta V$, $Delta y$ and $Delta I$ of wide visual double stars during the period 2003–2005. At least one component of the double stars in our sample has an entry in the Hipparcos catalogue.Aims. Our measurements are a contribution to the study of the nature of these double stars. Methods.The northern double stars of the project were observed with the 1.2 m telescope of the Kryonerion observatory and the southern with the 1.0 m SAAO. We performed multiple-exposure CCD imaging of our targets and used the standard procedure of data reduction and astrometric CCD calibrations. Results.We present measurements of 213 northern and 219 southern wide binaries.
