The single-piece primary and tertiary mirror blank cast for the LSST is "perfect", say project astronomers and engineers. The LSST, or Large Synoptic Survey Telescope, a large survey telescope being built in northern Chile, requires three large mirrors to give crisp images over a record large field of view. The two largest of these mirrors are concentric and fit neatly onto a single mirror blank.
