Timelapse footage of an astrophotographer tracking the night sky with a telescope. The telescope is mounted equatorially and driven by a motor to keep it pointed at the same object, so that a long-exposure photo can be taken. This clip shows the faint winter Milky Way and Sirius (the brightest star in the night sky). The astronomers are using red light to illuminate the scene as long wavelengths do not affect the dark adaptation of the eye. | |
