An f/100, 12.2-m focal length photoelectric telescope designed specifically for daytime astrometry of objects near the sun is now operative at its Tucson, Arizona, site. The design goal was to achieve accuracies of order 0.001 sec of arc in field position measurements of stars. To accomplish this, many features reducing systematic and random errors are employed, including Schupmann medial telescope optics, compensation for lateral color aberration, apodization for reduction of diffracted light, and use of an accurately measured solar diameter for calibrating the field.
一台专为对太阳附近天体进行白天天体测量设计的f/100、焦距12.2米的光电望远镜，目前正在亚利桑那州图森市的观测点运行。设计目标是在恒星的视场位置测量中达到0.001角秒量级的精度。为实现这一目标，采用了许多减少系统误差和随机误差的特性，包括舒普曼中望远镜光学系统、横向色差补偿、用于减少衍射光的切趾术，以及使用精确测量的太阳直径来校准视场。
