M45 is both known as "The Pleiades" or "The Seven Sisters". This is the best known open cluster in the sky due to its size and brightness. Mentioned frequently in ancient writings, the Pleiades contains over 250 members, with a dozen visible to the naked eye. The entire cluster is surrounded by faint wispy bluish nebulosity, visually hard to see, but dramatic in photographs. In scopes, you'll need a low power eyepiece in order to capture it in its entirety.
