这条恒星线是真实的。肯布尔的星群有点太暗，无法用肉眼看到，但当用双筒望远镜看到时，它会让人敬畏。和北斗七星一样，肯布尔的级联星是一个星群，而不是星座。在北部天空中可以看到长颈的长颈鹿星座（骆驼星座）。这条由大约20颗不相关的恒星组成的星链，每颗恒星的亮度相似，跨度超过满月角宽度的5倍。肯布尔的瀑布从左上到右下呈对角线延伸，上个世纪由天文学爱好者卢西安·肯布尔推广。图像左上角附近的明亮物体是相对紧凑的Jolly Roger疏散星团，官方命名为NGC 1502。

This line of stars is real. A little too faint to see with the unaided eye, Kemble’s Cascade of stars inspires awe when seen with binoculars. Like the Big Dipper though, Kemble’s Cascade is an asterism, not a constellation. The asterism is visible in the northern sky toward the long-necked constellation of the Giraffe (Camelopardalis). This string of about 20 unrelated stars, each of similar brightness, spans over five times the angular width of the full moon. Stretching diagonally from the upper left to the lower right, Kemble's Cascade was popularized last century by astronomy enthusiast Lucian Kemble. The bright object near the top left of the image is the relatively compact Jolly Roger open cluster of stars, officially designated as NGC 1502.
