The Dragonfly Telephoto Array is an array of 48 14-cm optical telescopes (actually commercially-produced cameras with telephoto lenses), a project of the University of Toronto, physically located at the New Mexico Skies observatory in New Mexico. The field of view of each is about six square degrees, and I presume they are pointed as identically as is practical. As a telescope, it has a large collecting area (currently roughly equivalent to a 1-meter aperture), giving it sensitivity for imaging very-large-scale diffuse extended sources, such as ultra diffuse galaxies. It began operation c2013 with 8 such cameras mounted together in a tight cluster, and now consists of two such clusters of 24 cameras each.
As of 2025, a follow-on named MOTHRA (for Modular Optical Telephoto Hyperspectral Robotic Array) with 1140 individual telescopes is in development to be deployed at Obstech Observatory in Chile.
An unrelated Dragonfly is the planned Dragonfly space mission to Saturn's moon, Titan.
