NGC6611

Constellation: Serpens
Eagle Nebula
As you can see this is an open cluster, it was discovered by Jean-Philipe de Cheseauz in 1745-46.  There are some460 stars associated with this this cluster, the brightest being a spectral class O, that is roughly 80 times the size of our sun, with a luminosity of up to a million times brighter than our sun.  (Bring a SPF 8million if you decide to visit this bad boy!)
The Eagle Nebula is part of an emission nebula or HII region, and active star formation and only 6,500 light-years away.  What I found interesting is that the intense radiation caused by the young stars, the pillers may already have boiled away, and are no longer there.  There is further evidence that a supernova exploded approx 6,000 years ago, we just have not had the light reach us yet, will be interesting to see what the new nebula looks like.
It is one of the more famious nebulas in the sky.  Hubble Space Telescope captured the 'Pillers of Creation'.  While you cannot really see the pillers in our image, I'm sure that it is there somewhere.
