The Evryscopes are a set of rapid-cadence, gigapixel-scale telescopes. Each instrument contains an array of up to 24 camera units, each consisting of a 6.1 cm (2.4 in) telescope (85 mm Rokinon DSLR lens) paired to a thermoelectrically cooled astronomical CCD. The camera units are arranged around a solid fiberglass structure to form a continuous field of view of 9216 sq. deg.[1]
The first instrument (Evryscope-South) was deployed in May 2015 to Cerro Tololo Inter-American Observatory, where it is co-located with the PROMPT Telescopes.[1] The second instrument (Evryscope-North) was deployed in October 2018 to Mount Laguna Observatory.[2]
Evryscope detected the first The First Naked-Eye Superflare Detected from Proxima Centauri. In March 2016, the Evryscope observed the first superflare that was visible to the naked eye from Proxima Centauri. Proxima increased in brightness by a factor of roughly 68 times during the superflare and released a bolometric energy of 10^33.5 erg, about 10 times larger than any previously detected flare from Proxima Centauri.[3]
Evryscope-South is funded by NSF/ATI and NSF/CAREER and was designed and built at the University of North Carolina at Chapel Hill.[1] Evryscope-North is funded in collaboration with San Diego State University.
The Argus Array Pathfinder, a technological successor with 38 cameras, was deployed in December 2022 at PARI, North Carolina. It serves as a prototype for the Argus Array, which will be a 900 camera survey instrument and replace the CCD technology with MOSFET detectors.[4][5]
