    The Wide Field Survey Telescope (WFST) is a Chinese telescope characterized by a 2.5-metre primary mirror, [1] dedicated to time-domain surveys, tracking objects that change during observation such as supernovae. [2] It saw first light on 17 September 2023 when the WFST imaged the Andromeda Galaxy. [3]
