The Pleiades is an open cluster located in the constellation of Taurus. At a distance of only 444 light years, its one of the closer open clusters. The dust surrounding them was originally thought to be left over from their formation, but it is now thought the cluster is moving through a dusty region of space. The blueish color of the surrounding nebula comes from light reflecting off the dust.
Known since ancient times, Charles Messier added it to his list of comet like objects in March 1769, even though it would be difficult to confuse them with a comet.

The Double cluster in Perseus is a pair of open clusters (NGC 869 and NGC 884) located in the constellation of Perseus. Both are young clusters at an age of around 12.8 million year old, and contain many blue-white super giant stars. The clusters are located 7,500 light years distant and are separated from each other by several hundred light years. They are located in the Perseus arm of the Milky Way Galaxy, while we are located in the Orion arm.

Messier 11 is an rich and compact open cluster located in the constellation of Scutum containing an estimated 2900 stars. It borders the northern end of the Scutum Cloud which is a dense section of the visible Milky Way. It's estimated age is between 220 and 250 million years. Like most open clusters, it's stars will eventually disperse through out the Milky Way. It was added to Charles Messier catalog in May, 1764.

An open cluster of stars in the constellation of Scorpio. The cluster consists of about 80 members, and lies at a distance of around 980 light years. Charles Messier cataloged the cluster in 1764. The cluster resides in front of the Milky Way backdrop showing a small sample of the estimated 100 billion stars that make up our Milky Way galaxy.
