Saturn in daylight.
Can you see planets during the day? Yes! Here is proof.
This photo was taken in the late afternoon through sunny blue skies. The moon and sun (with a solar filter!) were used to align and calibrate the GoTo computer in the telescope.
Slew the scope toward Saturn, move it around a little until it's seen in the view, and there it is!
This image is pretty sharp despite the daylight but it was nearly straight up also, which helps with the atmospheric "seeing".
