Star Trails Over Pines
Kodak Pro 400 PPF - 6 x 7 cm Pentax medium format w/55mm lens - 150 min
The setting for this star trails photo is what has been our primary spot for astronomy photography over the years, Mr. Pinos, California. It is a wonderful mountain covered with Lodgepole pines at 8350 feet where we set up our telescopes.
Star trails are made by the combination of: the spinning of the Earth, the use of a stationary mount or tripod and a long exposure of the film. As the Earth spins, the stars begin to make concentric circles on the photograph. The closer stars are to Polaris, our North pole star, the smaller their circles. Thar farther away they are, the larger their circles.
