Per scan step multiple images frames are captured that also get processed for enhanced image detail. A dual Fabry–Pérot imaging interferometer for the near-infrared. A cryogenic Czerny-Turner spectrograph for the 1 to 5 µm regime. A scanning echelle long-slit spectrograph. Goode Solar Telescope The Goode Solar Telescope (GST) is a scientific facility for studies of the Sun named after Philip R. Goode. It is the solar telescope with the world's largest aperture in operation. Located in Big Bear Lake; California, the Goode Solar Telescope is
