Star trails photography utilises long exposure times to capture the motion of the stars in the night sky due to the rotation of the Earth. The North Star marks the almost exact point where the Earth rotates on its axis, all the other stars rotate around this star giving that swirling effect you can see in the photographs. Finding the North Star is a key factor when setting up for a star trails shot but how do you find it? Easy! First find the Plough or commonly known as the Big Dipper, it looks like a giant dot to dot sauce pan! Follow the last two stars up in a straight line until you come to the next brightest star and you have found the North Star! For this type of photography you will need a camera that allows long exposure times of 15 seconds or more, a sturdy tripod, a cable release with locking mechanism, warm clothing, cloudless skies and lots of patience.
