Abstract
We are presently obtaining CCD V, R and I magnitude and colour differences for the individual components of a sample of selected “intermediate” visual double stars (with angular separations between 1 and 15”). Observations were performed with the CCD camera attached to the Ritchey- Chrétien focus of the 2m telescope of the Rozhen National Astronomical Observatory in Bulgaria. We present the photometric and astrometric results for two cases: the 9th mag standard star HD 218587, hereby reported as new visual double, and HIP 104210, a probable optical system with a higher proper motion foreground star.
