星际消光对反射星云NGC 1333周围暗云方向距离的依赖性是根据光电维尔纽斯光度测量和78颗恒星的光度分类确定的。在距离 160 和 220 pc 处注意到两个尘埃云。第一个平均消光为 0.4 星等的云属于金牛座云团，第二个平均消光为 1.8 星等的云属于乌云链和其他年轻天体，几乎垂直于旋臂，但位于银道面下方约 80 度。照亮 NGC 1333 星云的恒星 BD +30°549 距离太阳 212 pc。没有检测到英仙座云后面的灭绝增加。
The dependence of interstellar extinction on distance in the direction of a dark cloud around the reflection nebula NGC 1333 is determined on the basis of photoelectric Vilnius photometry and photometric classification of 78 stars. Two dust clouds are noted at distances 160 and 220 pc. The first one with mean extinction of 0.4 mag is concluded to belong to the Taurus cloud complex and the second cloud with mean extinction of 1.8 mag belongs to the chain of dark clouds and other young objects which is almost perpendicular to the spiral arm but lies ∼80 pc below the galactic plane. The star BD +30°549 which illuminates the NGC 1333 nebula is at distance 212 pc from the Sun. No extinction increase behind the Perseus cloud is detected.
