1978年3月9日和10日，在3.9m英澳望远镜的ƒ/15焦点上，用图像光子计数系统1对船帆和蟹状脉冲星进行了观测。使用皇家格林威治天文台(RGO)0.9米YAPP反射镜的电子相机获得了对Crab脉冲星非脉冲光的观测。我们获得了船帆2，3的相分辨照片，肯定地将它与微弱的蓝色候选恒星4进行了识别，并探测到了相对较强的非脉冲光成分。我们还探测到了蟹状脉冲星的一个微弱的非脉冲成分。
OBSERVATIONS of the Vela and Crab pulsars were made with the Image Photon Counting System1(IPCS) at the ƒ/15 focus of the 3.9 m Anglo–Australian Telescope (AAT), on 9 and 10 March 1978. Observations of the unpulsed light from the Crab pulsar have been obtained with an electronographic camera5used with the 0.9 m Yapp reflector of the Royal Greenwich Observatory (RGO). We obtained phase-resolved pictures of the Vela pulsar2,3, positively identifying it with the faint, blue candidate star4and detecting a relatively strong, unpulsed light component. We also detected a weak unpulsed component from the Crab pulsar.
