The **Evryscopes** are a set of rapid-cadence, [gigapixel](/source/Gigapixel)-scale [telescopes](/source/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](/source/Rokinon) [DSLR](/source/DSLR) lens) paired to a thermoelectrically cooled astronomical [CCD](/source/Charge-coupled_device). 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](/source/Cerro_Tololo_Inter-American_Observatory), where it is co-located with the [PROMPT Telescopes](/source/PROMPT_Telescopes).[1] The second instrument (Evryscope-North) was deployed in October 2018 to [Mount Laguna Observatory](/source/Mount_Laguna_Observatory).[2]

Evryscope detected the first The First Naked-Eye [Superflare](/source/Superflare) Detected from [Proxima Centauri](/source/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](/source/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](/source/National_Science_Foundation)/ATI and [NSF/CAREER](/source/National_Science_Foundation_CAREER_Awards) and was designed and built at the [University of North Carolina at Chapel Hill](/source/University_of_North_Carolina_at_Chapel_Hill).[1] Evryscope-North is funded in collaboration with [San Diego State University](/source/San_Diego_State_University).

The Argus Array Pathfinder, a technological successor with 38 cameras, was deployed in December 2022 at [PARI](/source/Pisgah_Astronomical_Research_Institute), 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](/source/MOSFET) detectors.[4][5]
