"Exactly what magnitude stars can be seen by day? Apparently the limit
runs from 1st to 4th magnitude, depending on the brightness of the sky.
The closer to sunrise, and sunset, the dimmer the stars that can be
detected. Indeed, several minutes before sunset [last fall, you could]
see many of Jupiter's moons through your scope! Can you see a shadow
crossing as well? I haven't tried it, but I bet you could!"
