Hobby-Eberly望远镜（HET）是一个创新的9.2米口径的大型望远镜，位于西德克萨斯州的麦克唐纳天文台。HET使用一个固定的分段主镜，并有一个跟踪器，它移动四镜校正器和主焦点仪器包，以跟踪天体的恒星和非恒星运动。HET的主要升级正在进行中，将通过更换校正器、跟踪器和主聚焦仪器包来大幅增加视野。除了支持现有的仪器套件外，这一宽视场升级还将为一台名为VIRUS的革命性新型积分场摄谱仪提供支持，以支持Hobby-Eberly望远镜暗能量实验（HETDEX）。本文讨论了这一升级的现状。
The Hobby-Eberly Telescope (HET) is an innovative large telescope of 9.2 meter aperture, located in West Texas at the McDonald Observatory. The HET operates with a fixed segmented primary and has a tracker which moves the fourmirror corrector and prime focus instrument package to track the sidereal and non-sidereal motions of objects. A major upgrade of the HET is in progress that will substantially increase the field of view by replacing the corrector, tracker and prime focus instrument package. In addition to supporting the existing suite of instruments, this wide field upgrade will feed a revolutionary new integral field spectrograph called VIRUS, in support of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). This paper discusses the current status of this upgrade.
