An Amateur Astronomer Photographed Star Cluster Pleiades

With a modified camera DSLR Canon 350D Baader Planetarium, an amateur astronomer made a picture of star cluster M45, also known as the Pleiades or the Seven Sisters, which is located in the constellation Taurus. Pleiades is the nearest star cluster to our planet, which can be seen with the naked eye. M45 can be seen in winter in the northern hemisphere and summer in the  southern  hemisphere.  Approximate  age  of the open cluster M45 about 100 million years. The diameter of the Pleiades is equal to 12 light years. It is assumed that the cluster consists of 3000 stars, among which are the hot blue stars. 14 of them are sometimes visible to the naked eye. The total mass of the stars of the Pleiades presumably equal to 800 mass of our sun.
