Milky Way Close-up Mosaic

This is a two-panel mosaic of the area around the core of our Milky Way galaxy. This area is where the constellations Sagittarius, Scutum and Serpens Cauda meet. The globular cluster M22 appears at lower left. The Lagoon Nebula (M8), the Trifid Nebula (M20) and the open cluster M21 appear at lower right. The Eagle Nebula (M16) and the Omega Nebula (M17) appear near the top middle of the frame. The area was fairly low in the sky when I took the shot (but it never gets very high at latitude 43.5 degrees north) and, unfortunately, was embedded in a considerable light-pollution dome from a nearby city, making background neutralization a challenge.
