An astronomical photograph was obtained with a multilayer x-ray telescope. A 4-centimeter tungsten-carbon multilayer mirror was flown as part of an experimental solar rocket payload, and successful images were taken of the sun at normal incidence at a wavelength of 44 angstroms. Coronal Si-XII emission from an active region was recorded on film; as expected, the structure is very similar to that observed at O-VIII wavelengths by the Solar Maximum Mission flat crystal spectrometer at the same time. The small, simple optical system used in this experiment appears to have achieved a resolution of 5 to 10 arc seconds.
用多层 X 射线望远镜获得了一张天文照片。作为实验性太阳火箭有效载荷的一部分，一个 4 厘米厚的钨-碳多层反射镜被发射升空，并成功地以 44 埃的波长对太阳进行了正入射成像。在胶片上记录到了日冕 Si-XII 发射；正如预期的那样，其结构与同时由太阳极大任务平板晶体分光计在 O-VIII 波长观测到的结构非常相似。在这个实验中使用的小型简单光学系统似乎已经达到了 5 到 10 角秒的分辨率。
