deep sky object
Distant astronomical body
A deep sky object is any celestial body outside our solar system—galaxies, nebulae, star clusters—typically observed through telescopes.
The term distinguishes these distant targets from nearby objects like planets and moons.
Amateur astronomers catalog and hunt deep sky objects: I spent the night photographing deep sky objects in Orion.
