DEEP-SKY ASTROPHOTOGRAPHY — PROCESSED IN PARIS
Galaxies
The Moon, the Sun, the planets and a few passing comets — targets measured in minutes and frames rather than hours. Most are imaged at high frame rate, then stacked, keeping only the sharpest fraction of each sequence; comets get classic long exposures, short enough to freeze their motion against the stars.
