These videos were made while the laser guide star system of CANARY
was being used at the William Herschel Telescope on 29 June, 2015. CANARY is a wide-field laser guide star tomography and open-loop AO (MOAO) demonstrator with the goal of emulating a single channel of the proposed E-ELT MOAO instrument, EAGLE, albeit at 1/10th scale. By coincidence the videos were obtained on the night the King of Spain, Felipe VI, was invited to join the observations at Gran Telescopio Canarias (GTC) to commemorate the 30th anniversary of the inauguration of the Canarian Observatories.
