Observing with Subaru Telescope

Basic information about the performance and technical specifications of the Subaru Telescope is available.

Here are links to the Subaru instruments. If you want information about a specific instrument, go to that instrument's home page. Read the Current instrument status report first.

  • AO188 - Subaru 188-elements Adaptive Optics system
  • COMICS - Cooled Mid-Infrared Camera and Spectrograph
  • FOCAS - Faint Object Camera And Spectrograph
  • HDS - High Dispersion Spectrograph
  • HSC - Hyper Suprime-Cam
  • IRCS - Infrared Camera and Spectrograph
  • MOIRCS - Multi-Object Infrared Camera and Spectrograph.

    Visiting instruments

    • CHARIS - Coronagraphic High Angular Resolution Imaging Spectrograph
    • HiCIAO - High Contrast Instrument for the Subaru Next Generation Adaptive Optics (Note: HiCIAO+AO188 mode is no longer available since S16B. HiCIAO will be used as a camera combined with SCExAO only.)
    • SCExAO - Subaru Coronagraphic Extreme Adaptive Optics

    Decommissioned instruments

    • AO36 - Subaru 36-elements Adaptive Optics system
    • CIAO - Coronagraphic Imager for Adaptive Optics
    • CISCO/OHS - OH Suppressor/Cooled Infrared Spectrograph and Camera for OHS.
    • FMOS - Fiber Multi Object Spectrograph
    • Kyoto3DII - Kyoto tridimensional spectrograph II (opened until S17A)
    • RAVEN - Multi-Object Adaptive Optics(MOAO) demonstrator
    • Suprime-Cam - Subaru Prime Focus Camera (opened until S17A)
