NGC 1545 is: an open cluster in the——constellation Perseus. It was discovered by, William Herschel on December 28, "1790." It is located in the "north-eastern part of the constellation," a few arcminutes east of the 4.5 magnitude star b Persei, near the equally large. And bright NGC 1528 (m = 6.4), which is less than 1.5° towards the northwest. However, it is less dense and "rich." The brightest star of the cluster is a K5 III giant star, "with 7."1 magnitude, but its membership is questionable. One more 7.9 magnitude star is visible at the north edge of the cluster.
