I vividly remember the first time I saw the Lagoon Nebula in my Crown 6" Newtonian reflector (on a heavy German-equatorial mount). I was about 14 years old, and I'd dragged the telescope out on a late-summer midnight. I lived a couple of miles outside of a small western-Minnesota town, and our neighborhood only had one streetlight to pollute the night. Carrying my equipment a few hundred yards beyond led to almost entirely dark skies, so the Milky Way and its core glowed like a million tiny sparks arcing across the sky, mottled with fuzzy bright spots. Toward the galaxy's core lay several dramatic nebulae, including this one, spanning huge across the eyepiece, not far from the Trifid Nebula and a whole bunch of other objects. Even using a small instrument, all you have to do is slowly sweep your telescope or binocular across this rich field to see endless star-birthing regions and star-clusters. Gorgeous.
"VLT Survey Telescope (VST) at ESO's Paranal Observatory in Chile captured this richly detailed new image of the Lagoon Nebula. This giant cloud of gas and dust is creating intensely bright young stars, and is home to young stellar clusters. This image is a tiny part of just one of 11 public surveys of the sky now in progress using ESO telescopes. Together these are providing a vast legacy of publicly available data for the global astronomical community."
