Star Trails Timelapse 

A Star Trails Timelapse during the Perseid Meteor Shower
Just like a painter uses a brush to create beautiful art, photographers use the passage of time and the rotation of our Earth to paint the night sky with the light of countless stars. By leaving the camera's shutter open for an extended period, the stars' motion turns into majestic arcs of light that streak across the night sky.
Look at those graceful, circular paths! They are so beautiful!
