Former Constellations
Constellations are not fixed and have evolved over time. Before the standardization of constellations in 1922, different civilizations designated their own constellations. The Western canon now dominates, but many constellations designated by telescopic observers in the Southern Hemisphere no longer exist. Examples include Quadrans Morales and old maps depict constellations that are no longer recognized.
