The Liverpool Telescope has a number of sky cameras (or SkyCams) that can take wide field photos whilst the telescope is observing. The current SkyCam system has 3 cameras:

  • SkyCam A - is an "all sky" camera which is fixed to the inside of the telescope enclosure. It uses a fish-eye lens to give almost all-sky views of the stars visible to the naked eye. Whilst giving an amazing view of the night sky, it is also useful for checking for clouds.
  • SkyCam T - is a "medium field" camera fixed to the telescope. It points wherever the telescope is pointing. The camera gives a 21° field-of-view and can detect sources down to about 12th magnitude. The larger field of view is useful for seeing the space around the thing being observed. It can be used to spot asteroids, satellites and even shooting stars.
  • SkyCam Z - is a "zoomed field" camera. It is also fixed to the telescope and points in the same direction. It looks at a 1° area of sky around 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.
