Viewing the nebula from the right place and the right direction, a naked-eye observer could probably get a pretty well-lit view of it all. I couldn't say for sure, though.

Interestingly, it is the intense radiation flux and stellar wind from the stars in NGC 6611 that is believed to be responsible for forming those incredible pillar and tower structures in the gas clouds. The "heads" of the pillars are regions of dust/gas that are denser than the surrounding regions, and thus aren't dissipated as easily by the radiation; and the bodies or "stems" of the pillars are formed by gas/dust that is in the shadows of these dense regions and thus remain in place while the rest of the gas/dust around them blows away. Also interestingly, there is evidence that a supernova actually completely destroyed (blew away) the "Pillars of Creation" and many other distinctive Eagle Nebula features six thousand years ago, but we won't know for sure for another thousand years, since they're seven thousand light years away.

Yes I remember hearing about how radiation pressure formed the structure of this nebula, though I don't remember as many details as you have. That's pretty cool.

I'm a little surprised, however, that we have evidence for a supernova destroying this structure 6k years ago... how could we possibly have this information before we see it? It's obvious that we don't have direct information about this event, as we if did we would have received this information faster than the speed of light. Is this speculated from the phase and size of the star whose supernova is thought to have destroyed this nebula?
