429 CCD measurements of relative positions and magnitude differences in V and R photometric bands for 165 visual double and multiple stars are given. CCD frames were taken at the 1.52 m Spanish telescope of the Spanish-German Center of Astronomy at Calar Alto (Almería, Spain). During the reduction process a “Tepui" function was used as the PSF function.
