NGC 1545 is an open cluster in the constellation Perseus. It was discovered by William Herschel in 1790. It is located in the north-eastern part of the constellation, 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 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.
