A photographic coronagraph, built to monitor Skylab's extravehicular contamination, is described. This versatile instrument was used to observe the earth's vertical aerosol distribution and Comet Kohoutek (1973f) near perihelion. Although originally designed for deployment from the solar airlock, the instrument was modified for EVA operation when the airlock was rendered unusable. The results of the observations made in four EVA's were almost completely ruined by the failure of a Skylab operational camera used with the coronagraph. Nevertheless, an aerosol layer at 48 km was discovered in the southern hemisphere from the few useful photographs.
描述了一种用于监测天空实验室舱外污染情况的摄影日冕仪。这种多功能仪器被用于观测地球垂直方向的气溶胶分布以及科胡特克彗星（1973f）近日点附近的情况。尽管该仪器最初设计为从太阳能气闸舱进行部署，但当气闸舱无法使用时，它被改装用于舱外活动操作。在四次舱外活动中进行观测所获得的结果，几乎完全因与日冕仪一起使用的一台天空实验室操作相机出现故障而毁于一旦。然而，从少数几张有用的照片中，在南半球发现了一个位于48千米高度的气溶胶层。
