This is a 4.5 hour LRGB exposure of this striking nebula. The Trifid Nebula in Sagittarius is a remarkable and beautiful object as it consists of both a conspicuous emission nebula (the red glow) and a remarkable reflection nebula (the blue glow). This object is inside our galaxy and that's the reason for the heavy population of stars throughout this image. The image was taken over 3 nights beginning on June 10, 2013. Click for a closer view.
