Abstract

Relative positions and separations for 65 visual binaries are given. CCD frames were taken at the 1-m coudé telescope and micrometric observations were carried out at the 65-cm refractor, both at the Venezuelan National Observatory. The visual double stars observed were selected from the Ramón María Aller Observatory program list. In addition, we also observed several long period double stars with poorly determined orbital elements.
