An objective-prism stellar spectrograph of 15-cm aperture was flown on all three Skylab missions. The wavelength region from 1300 A to 5000 A was covered by a special optical system containing a combination of reflecting telescope optics, a CaF(2) objective prism, and an achromatized field corrector lens system of CaF(2) and LiF. Observations of 188 star fields, each covering 4.0 degrees 5.0 degrees , were conducted at the Skylab antisolar airlock with the aid of an articulated mirror system (AMS) which allowed acquisition within 30 degrees degrees 360 degrees band of the sky.
一台口径为15厘米的物端棱镜恒星摄谱仪搭载在所有三次天空实验室任务中。1300埃至5000埃的波长区域由一个特殊光学系统覆盖，该系统包含反射望远镜光学元件、一块CaF₂物端棱镜以及一个由CaF₂和LiF组成的消色差场校正透镜系统。在天空实验室背阳气闸舱借助一个关节镜系统（AMS）对188个星场进行了观测，每个星场覆盖4.0度×5.0度，该关节镜系统允许在天空30度×360度的波段内进行目标捕获。
