70mm (57x) At 57x nothing seen at first sight. At 133x the much fainter component was visible after a short time as a tiny star in the correct position angle. With this knowledge, the observation at 57x was also successful, even if one has to look very closely. The challenge here is not so much the angular distance as the large difference in brightness.
