Deep Sky

Deep-sky objects are celestial targets located far beyond our Solar System, ranging from structures within our own Milky Way to galaxies at immense cosmological distances. They reveal many different stages and scales of the Universe, from the birth and death of individual stars to enormous systems containing billions of them.

The main subjects of deep-sky astrophotography include nebulae, vast clouds of gas and dust; star clusters, families of stars sharing a common origin; galaxies, immense stellar systems beyond the Milky Way; groups of galaxies, gravitationally associated collections of galaxies; and supernovae and their remnants, the spectacular explosions of stars and the structures they leave behind.

Photographing these extremely faint objects generally requires long exposures and many hours of accumulated light, revealing details, colours and structures that our eyes alone cannot see.
