The stars overhead at night in the summer tend to be overhead at day in the winter. For instance, in the northern hemisphere's summer we look in towards the milky way center at night, but during winter nights we look out towards the great unknown. That said, I suppose you could train your camera at Polaris and depending on your latitude (the northern the better, but don't go so far that you lose nights) you'll have a consistent circle around 90-Lat degrees wide. A bit less due to axial tilt, but I'm not exactly sure how much.
