The telescope is shown from the NFIRAOS-IRIS Nasmyth platform in an inclined position, shooting its laser guide star towards a starry cloudless night sky. An orange light is still turned on within the enclosure to show the details of the telescope structure. The WFOS instrument (seeing-limited multi-object visible spectrograph) is shown across the primary mirror, sitting on the other Nasmyth platform. The enclosure cover can be seen across the dome, behind the rotating enclosure structure, in its fully retracted position, ready for astronomical observations.
