NGC 6820/3
NGC 6820 is a diffuse emission nebula that surrounds the open cluster of stars NGC 6823 (at the center of the image). The intense light from the hot, massive stars in the cluster is blowing away the gas in the nebula, causing the distinctive 'pillar' shapes on the left side of the image.
