Stars twinkle due to atmospheric refraction. In the same way that your TV combines RGB to make a multitude of colors, the combined light data from 1+ minute of video creates close approximation of the true color.
Wrong
several times during winter, I'd see the stars flash several colors, then they'd somehow all turn white and stop twinkling. I'd also see stars just get up and move around sometimes, at a brisk pace.
Because When they are lower in the sky there is more atmosphere for the light to pass through (therefore more refraction), then when they get up high the light can take a straighter path. Also, some of those instances you may have been mistaking Mars, Jupiter, or Saturn for a star. They certainly look like stars to the naked eye.
whoah there pal, i didn't say i was using just the naked eye. I like to use binoculars. admittedly I don't have the best, I have some Companion 10x42 binoculars. i seen big stars move with the naked eye, but that's rare. i used to see even more tiny ones move with the binoculars.
but in the summer in this undisclosed location, i don't see the stars at all right now. i know what i do or don't see.
