Laser Guide Star at Gemini North

Here is a time-lapse movie of the Gemini North observatory during a Laser Guide Star (LGS) run, taken from the catwalk around the outside of the UH 2.2 meter telescope. LGS creates an “artificial star” which is used as a reference source for adaptive optics systems on Gemini instruments. Directly behind the Gemini Observatory is the Canada-France-Hawaii Telescope (CFHT). Gemini Observatory Image/Video Usage Policy HD Quicktime Movie (48.9 Mb) iPhone Movie (2.3 Mb)
