The Large Synoptic Survey Telescope (LSST) (original) (raw)

The Large Synoptic Survey Telescope (LSST) will be a large, wide-field ground-based telescope designed to obtain sequential images of the entire visible sky every few nights. The optical design involves a novel 3-mirror system with an 8.4 m primary, which feeds three refractive correcting elements inside a camera, thereby providing a 7 square degree field of view sampled by a 2.3 Gpixel focal plane array. The total system throughput, AΩ = 270 m 2 deg 2 , is nearly two orders of magnitude larger than that of any existing facility.
