An exciting time for a new telescope is "first light," when the first images are taken. This picture is "first blast" for the Large Synoptic Survey Telescope LSST at Cerro Pachon. They've begun leveling the ground for the telescope's base. I joined the "LSST Science Collaboration" and have been working on astrometry issues.
There's even an LSST webcam so you can watch the leveling.
