WiFeS is an integral-field, or imaging, spectrograph, meaning that it records a spectrum from each pixel of the region that is imaged. WiFeS was designed and built at RSAA and installed at the 2.3m telescope in May 2009.
DECOMMISSIONED: The Dual-Beam Spectrograph was a general purpose optical slit spectrograph that was mounted at the Nasmyth A focus of the ANU 2.3m telescope.
DECOMMISSIONED: The 2.3m Echelle was a high-resolution echelle spectrograph that operates at mid-optical wavelengths, previously mounted on the ANU 2.3m telescope.
DECOMMISSIONED: The tiptilt system was developed at RSAA for the 2.3m telescope, to correct motion of the guide star caused by atmospheric seeing and guide errors.
