First light image from the Kepler space telescope with two points of interest outlined. Celestial north is toward the lower left corner.[1]
In astronomy, first light is the first use of a new instrument, typically a telescope, to take an astronomical image after it has been constructed.[2] This is often not the first viewing using the telescope, as optical tests are usually performed beforehand to adjust the components.
