You can appreciate an attractive open cluster of NGC1528 about 8 degrees east of alpha Persei. The constellation of Perseus is ornamented by some superb clusters of The Double Cluster, M34 etc. And of course the cluster of NGC1528 should be included in those splendid objects.
The cluster is just bathed in the Milky Way; it's easy to detect snuggling members of the cluster only with portable binoculars. You'll be able to count about 80 fine stars spreading into 24 arc minutes or so. And this picture shows you another reddish nebula of NGC1491 about 2 degrees west of NGC1528. We cannot appreciate the H-alpha emission nebula with naked eyes. The minor nebula has a diameter of about 3 arc minutes, being nearly a circle. And a compact and indistinct reddish nebula between them has an ID of Sh2-209.
