Robo-AO time lapse laser movie - January 2013
Published on Jan 30, 2013
Time-lapse video of the ultra-violet (UV) laser guide star used by the Robo-AO adaptive optics system. Although the laser is invisible to the human eye, it shows up in digital SLR cameras once their internal UV blocking filters are removed. The apparent color of the laser beam is a result of the UV light leaking through the camera's red, green and blue pixel filters by slightly different amounts.
