NGC 4755, The Jewel Box Cluster is a young open cluster in the southern constellation of Crux. Taken with a remote scope in Australia while I waited out the clouds here. One of the youngest open clusters near us at an estimated age of 14-16 years, it contains many super-giant stars that haven't had time to burn through their fuel at their furious rate.

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.
