(HET)
(9.2 meter telescope in Texas)

The Hobby-Eberly Telescope is a 9.2 meter Reflector Telescope in Texas that is part of the McDonald Observatory. It opened in 1996. It has a Segmented Mirror consisting of 91 hexagonal mirror segments. Instruments:

In development:

  • VIRUS - "Visible integral-field replicable unit spectrograph"
  • HRS-2 - "high resolution spectrograph".
  • HPF - "habitable-zone planet finder"

Former instruments:

  • HRS - "high resolution spectrograph"
  • MRS - "medium resolution spectrograph"
  • LRS - "low resolution spectrograph"

Its instruments are used for the HETDEX survey, i.e., Hobby-Everly Telescope Dark Energy Experiment.

Southern African Large Telescope (SALT) was originally planned to be a copy of the Hobby-Eberly Telescope which has the same spherical Primary Mirror but SALT includes some significant changes.
