A star trail is a sort of photo that uses long-introduction times to catch the clear movement of stars in the night sky because of the Earth’s pivot. A star trail photo shows individual stars as streaks over the picture, with longer exposures bringing about longer streaks. Run of the mill presentation times for a star trail range from 15 minutes to a few hours, obliging a “knob” setting on the camera to open the shade for a more drawn out period than is typical. Star trail photos are conceivable in light of the Earth’s revolution on its hub. The obvious movement of the stars is recorded as streaks on the film or locator.
