Abstract
We present angular separations, position angles and Delta V instrumental ma gnitude differences of 83 visual double stars with angular separations arou nd two arcseconds. Our observations were made by means of a CCD detector at tached to the Kryonerion 1.2 m telescope. 12 of them are common proper moti on stars and their components should therefore be stars of common origin.
