The orbit period of the Zubenelgenubi binary system is 5870 days (not 5870 years) or about 16 years.

Dave,
It is safe to say that you have spotted Zubenelgenubi and can check it off your list. The give away is that Zubenelgenubi is a binary star (period 5870 years) and the pair can be seen through 7x50 binoculars with no trouble. Even my poorly taken 200mm telephoto snap shows the binary pair. The internet image shows better but is probably an animation. Using a x4 scope on a Plath had Zubenelgenubi visible 15 minutes into nautical twilight (0613 PST at 34N 119W).
