    Re: Could I have seen Zubenelgenubi in morning twilight with x10 binoculars?

    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).

    Yes, that’s what I saw, but just bright dots in my case, nothing like the detail in your photograph.  Also, it was lighter, more like in this chap’s photo https://jeffreylhunt.wordpress.com/2017/12/16/2017-december-16-jupiter-and-mars/ , except that for me it was a bit lighter still, so only Jupiter was visible to the naked eye.  DaveP
