Nebula HDR screensaver

Dust, reflected starlight, and a camera that goes somewhere: • Dust lanes carve dark channels through the clouds, and dense foreground dust now reaches real opacity, cutting silhouettes out of the star field behind it • The gas is filamentary instead of billowing — masses gather into streamers and sheets rather than round lumps • The brightest stars light the gas they sit in, with a blue-white reflection glow that only appears where there is cloud to scatter it • The camera reads the sky ahead
