Comment:
NGC 457 is a nice open cluster consisting of more than a hundred stars within volume of 30 ly in diameter. Two brightest stars visible on the image (forming "eyes" of the owl) are not members of the cluster. They are in fact foreground stars. NGC 457 is 9300 ly distant and some 8 million years old.
