Time lapse: Mauna Kea Lasers
Beautiful work from Sean Goebel:
This montage was filmed on three nights in April (I was observing on one of the telescopes and would walk outside when things got boring) and four nights during summer 2013. More information (i.e. “What’s up with the lasers?” “What gear did you use?”) can be viewed here.
Colossal notes, “The lasers you see are called laser guide stars and they help astronomers correct the atmospheric distortion of light by creating an artificial “star” to use as a reference point. “ [Vimeo]
