Greg, you asked Geoffrey:
"would you think you could see Polaris during the day at 40 deg Lat?"
You can, but you need magnification and a very clear sky. Magnification increases the contrast of the sky. It makes the background blue deeper so it's easier to see a second-magnitude star like Polaris. If the sky is clear blue, and you aim a telescope with magnification 25x or better at the right coordinates, you can see Polaris in daylight.
Geoffrey, what has your experience been? Have you seen Polaris in daylight in the desert? How about in Scotland (higher Polaris altitude but presumably lower transparency).
