格雷戈尔望远镜的机械结构于2004年安装在特内里费岛的泰德天文台。介绍了1.5米主镜安装和冷却的新概念。格雷戈尔是一个开放式望远镜，因此穹顶在观测期间是完全开放的，以允许空气通过开放但僵硬的望远镜结构涌入。主镜的背面冷却系统将镜面保持在接近环境温度的位置，以防止看到镜面。主镜的收集面积较大，导致主镜主焦处的场止点能量密度较高，需要去除。光学元件由精密对准系统支撑，应能在光学实验室提供稳定的太阳图像。列车可以进行疏散，是外部环境条件和带有灵敏科学仪器的空调光学实验室之间的天然屏障。该望远镜已成功投入使用，并将于2013年开始名义运行(2012 Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
The mechanical structure of the GREGOR telescope was installed at the Observatorio del Teide, Tenerife, in 2004. New concepts for mounting and cooling of the 1.5-meter primary mirror were introduced. GREGOR is an open telescope, therefore the dome is completely open during observations to allow for air flushing through the open, but stiff telescope structure. Backside cooling system of the primary mirror keeps the mirror surface close to ambient temperature to prevent mirror seeing. The large collecting area of the primary mirror results in high energy density at the field stop at the prime focus of the primary which needs to be removed. The optical elements are supported by precision alignment systems and should provide a stable solar image at the optical lab. The coude train can be evacuated and serves as a natural barrier between the outer environmental conditions and the air-conditioned optical laboratory with its sensitive scientific instrumentation. The telescope was successfully commissioned and will start its nominal operation during 2013 (© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
