M45. The Pleiades star cluster, also known as the Seven Sisters. |
M46 is a rich open star cluster. The bright red object near the center is NGC 2438, a planetary nebula. NGC 2438 is not a part of M46 and just happens to be in the same line of sight as the star cluster. |
NGC 281 is very faint to the naked eye, but is a pretty impressive photographic object in the constellation Cassiopeia. |
