Abstract. Optical speckle masking observations of 32 binary and multiple stars with the SAO 6-m telescope are presented. The resolution of the reconstructed diffraction-limited images is 23 mas at 656 nm. Accurate magnitude differences were first determined for most binaries. The results for individual systems are compared with the available orbits and with published photometric data. A new close visual component was discovered in the multiple system ADS 784.
