The Large Synoptic Survey Telescope (LSST) is a wide-field survey reflecting telescope with an 8.4-meter primary mirror,[10][11] currently under construction, that will photograph the entire available sky every few nights.[12] The telescope uses a novel 3-mirror design which delivers sharp images over a very wide 3.5-degree diameter field of view, feeding a 3.2-gigapixel CCD imaging camera, the largest digital camera ever constructed.[13]
