The Liverpool Telescope is fitted with a number of sky cameras (or SkyCams) that can take wide field observations whilst the telescope is observing. At present, the SkyCam system consists of three cameras:

  • SkyCam A - is an "all sky" camera on a fixed mount inside the telescope enclosure. It uses a fish-eye lens to provide near all-sky coverage of stars visible to the naked eye. In addition to providing a fascinating view of the night sky, this camera is useful for checking for the presence of clouds.
  • SkyCam T - is a "medium field" camera that is fixed to the telescope and points in the same direction. The camera provides a 21° field-of-view and can detect sources down to about 12th magnitude. The larger field of view is useful for seeing the region around the target being observed, and can be used to spot asteroids, satellites and even shooting stars.
  • SkyCam Z - is a "zoomed field" camera that is fixed to the telescope and points in the same direction. It captures a 1° area of sky in the immediate vicinity of the target being observed, and can detect objects down to about 18th magnitude. The data from this camera is not available until 18 months after it was taken.
