Yesterday, several of us looked at Jupiter during the day without optical aid.
I had been looking at it just after sunset the previous day, so I know about
where to point my telescope. After putting the scope on it, we looked through
the Telrad, and there it was at 6:30 p.m.
The best time to look is in the last half hour before sunset. Start by looking
due south (usually easy to do in Phoenix) about one-third of the way from the
horizon to the zenith, and then move your gaze about half of this angle (15
degrees) to the left. The problem is focusing your eyes to infinity. Like the
lens on my annoying old point-and-shoot camera, I just can't switch my eyes'
auto-focus off. A polarizing filter darkens this part of the sky a lot.
