Canary AllSky Camera

The Canary AllSky Camera is a special low-light camera that captures a 180° field-of-view of the skies above the observatory. It runs 24hrs and is ideal to check sky conditions that may affect imaging. The time-lapse from it is regularly updated and makes it easy to identify haze. You can also use it to capture the constellations, Milky Way, meteors whizzing across the sky, as well as the International Space Station and other satellites as they pass over the observatory. You may sometimes see a green laser pointing skyward from one of the professional telescopes undertaking "quantum cryptology" experiments to orbiting satellites.
