干草堆望远镜是一种直径为37米的天线，其表面高度精度为≤100μm，能够进行毫米波观测。雷达罩封闭式仪器用作空间态势感知的雷达传感器，大约三分之一的时间可用于麻省理工学院干草堆天文台的研究。正在对K波段(18-26 GHz)和W波段(目前为85-93 GHz)接收器进行测试，准备将该望远镜纳入事件视界望远镜(EHT)阵列，并将其用作单碟式研究望远镜。鉴于其地理位置，将干草堆望远镜添加到当前和未来版本的EHT阵列将大大提高图像质量。
The Haystack Telescope is an antenna with a diameter of 37 m and an elevation-dependent surface accuracy of ≤100μm that is capable of millimeter-wave observations. The radome-enclosed instrument serves as a radar sensor for space situational awareness, with about one-third of the time available for research by MIT Haystack Observatory. Ongoing testing with the K-band (18–26 GHz) and W-band receivers (currently 85–93 GHz) is preparing the inclusion of the telescope into the Event Horizon Telescope (EHT) array and the use as a single-dish research telescope. Given its geographic location, the addition of the Haystack Telescope to current and future versions of the EHT array would substantially improve the image quality.
