Submission + - 'Perfect' Mirrors Casted for LSST (

eldavojohn writes: The Large Synoptic Survey Telescope (partially funded by Gates & Co.) announced a world record casting for its single-piece primary and tertiary mirror blanks as they were created at the University of Arizona. From the announcement, "The Mirror Lab team opened the furnace for a close-up look at the cooled 51,900-pound mirror blank, which consists of an outer 27.5-foot diameter (8.4-meter) primary mirror and an inner 16.5-foot (5-meter) third mirror cast in one mold. It is the first time a combined primary and tertiary mirror has been produced on such a large scale."
