A rising telescope under a rising Sun and Moon!

This montage offers a kaleidoscope of moments from the construction of our Extremely Large Telescope (ELT), each one perfectly framed by the #Sun and #Moon behind it.

Creating this collage was no small feat: it took Boris Häußler, an ESO astronomer in #Chile, years of meticulous planning to time each frame almost down to the exact second.
