Abstract:
We present angular separations, position angles and ΔV
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 1.2m telescope.
12 of them are common proper motion stars and their components should
therefore be stars of common origin.
