Abstract
We present angular separations, position angles and
instrumental magnitude differences of 83 visual double
stars with angular separations around two arcseconds.
Our observations were made by means of a CCD detector attached to
the Kryonerion 1.2 m telescope.
12 of them are common proper motion stars and their components
should therefore be stars of common origin.
Key words: stars: binaries: visual / astrometry
Based on observations made at Kryonerion Observatory, Greece.
