- Astrophotography — A specialized branch of practical astronomy and photographic art that deals with photographing celestial bodies, constellations, planets, and deep-sky objects (nebulae, galaxies, star clusters). It involves advanced long-exposure techniques, automated star tracking, and digital processing (stacking and calibrating frames) to reveal details invisible to the human eye due to extremely low luminosity.
- Astrography — A descriptive branch of practical astronomy or an archaic terminological variant for astrophotography, having as its object the description, mapping, and cataloging of celestial bodies through images obtained using an astrograph. In a historical sense, it represents the technique of printing and faithfully reproducing star charts or photographic plates based on silver emulsion, used intensively in major international sky inventory projects of the 19th and early 20th centuries.
