M45: The magnificent Pleiades (seven sisters) star cluster
With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The featured exposure took over 12 hours and covers a sky area several times the size of the full moon.
Also known as the Seven Sisters and M45, the Pleiades lies about 400 light years away toward the constellation of the Bull (Taurus). …The actual number of Pleiades stars visible, may be more or less than seven, depending on the darkness of the surrounding sky and the clarity of the observer’s eyesight.
