deep sky
Beyond our sun
Deep sky refers to celestial objects beyond our solar system—galaxies, nebulae, star clusters, and other distant phenomena.
The term distinguishes these faint, remote targets from nearby objects like planets and the moon.
Amateur astronomers speak of deep sky observing or deep sky photography, pursuits that typically require dark skies and specialized equipment to capture objects millions of light-years away.
