Construction of astronomical camera captured on time-lapse video

New Scientist : It took about 10 months at Fermilab in Illinois to build a camera capable of detecting evidence of dark energy’s effects on the distribution of galaxies, but now you can watch the construction and testing in 3 minutes 45 seconds, thanks to a new time-lapse video , set to the tune of Johann Pachelbel’s Canon in D major. The camera, whose resolution is second only to the Pan-STARRS telescope, will be installed next year on the Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile.
