M16 (NGC 6611)
M16 is an interesting target in many aspects and first discovered in 1745 by Jean-Philippe de Cheseaux. It took about two centuries and the availability of photographic astronomy that this is much more than an open star cluster.
The Eagle Nebula is in fact an active starforming region within a large region of Hydrogen-Alpha. It is the home of quite prominent "columns" of dust and molecular Hydrogen, which are better known as the Pillars of Creation after the Hubble Space Telescope took a colorful picture in 1995.
