If you are in the Northern Hemisphere and want the stars to draw concentric circles in the sky, you have to individuate and frame Polaris. To record star trails in your photography, all you need to do is take a long exposure of the sky. You can take advantage of the different motions of stars to photograph landscapes with different kinds of star trails. Knowing the way stars move is important for star trail photography. Note as Polaris remains almost fixed in the North sky. Simulated star trails when looking North (top) and East (bottom). To easily spot the different way stars move if you look in different directions, I created star trails from the two gifs above. This time they move in a rather straight line. Stars appear to move slightly differently if we look at the East sky. The gif shows how stars move in a circle around the North celestial pole, roughly indicated by Polaris, the North Star. This is a fast-forwarded image (stars do not move this fast), and you are looking at the sky toward the North (note the presence of the Polaris). To give you an idea of how stars move, I created the gif below with the free astronomy software Stellarium. This image shows how Earth rotates on its axis, which is tilted with respect to Earth’s orbit. ![]() When you glance at the stars, you might think that nothing up there is moving, but in reality the night sky is very dynamic.Įarth’s rotation around its axis is the main reason for the apparent motion of stars in the night sky.
