IC 4812 NGC 6723 LRGB
a rich star field where NGC 6723, a dense globular cluster (upper left), contrasts with IC 4812, a wispy blue reflection nebula (center-right). The cluster appears as a tight, grainy sphere of ancient stars, while the nebula glows softly as starlight scatters off interstellar dust, all set against a deep Milky Way backdrop sprinkled with countless stars.
