Uranian Midpoint Calculator

A planetary picture is the central interpretive unit of Uranian astrology, the system Alfred Witte and the Hamburg School developed in 1920s Germany. It exists when the midpoint of two chart factors lands on a third factor within a tight orb, written A/B = C and read as "the combined symbolism of A and B focuses through C." Witte's collaborators Friedrich Sieggrün and Hermann Lefeldt formalized the technique in Rules for Planetary Pictures; Reinhold Ebertin extended it through cosmobiology and the 90° dial in The Combination of Stellar Influences.

This scanner operates in 90° space, so a single midpoint catches matches across all four cardinal harmonics (conjunction, square, opposition, and the half-square family) in one sweep. Optional Trans-Neptunian Points let you include Witte's eight hypothetical bodies (Cupido, Hades, Zeus, Kronos, Apollon, Admetos, Vulcanus, Poseidon) for advanced analysis. For a deeper guide to reading the equations, see the planetary pictures guide with worked examples.

This tool is the equation and table viewof Uranian midpoint analysis. It returns every A/B = C planetary picture in your chart, a sortable midpoint table in 90° space, the Basic Five personal-axis filter, and keyword chips for synthesis. If you want to see these structures laid out on a circular dial instead of read them as equations, use the 90° Dial for the visual companion. Most Uranian readers use both: the dial to spot patterns, the scanner to read them out.

Start with the Basic Five, the five personal axes that form the foundation of Uranian chart reading: the Midheaven (MC), the MC/Sun midpoint, the MC/Ascendant midpoint, the Ascendant, and the Ascendant/Sun midpoint. Any factor or midpoint matching these axes can be read as personal-axis testimony around identity, public role, and how you meet the world.

Each match shows the equation (e.g., Mars/Jupiter = MC), the orb of the match, and keyword chips drawn from the factors involved. The keywords are a starting vocabulary for synthesis. Combine the themes of each factor to build a meaningful interpretation. Mars (drive) plus Jupiter (expansion) on the MC (public role) can suggest ambitious public-role testimony that grows visibly over time.

Switch to Full Analysis for the complete midpoint table and every detected planetary picture. Use the sortable midpoint table to find where specific midpoints land in 90° space, then check whether any natal factor or TNP occupies that degree within your chosen orb.

Suppose your Sun sits at 12° Leo and your Moon at 18° Libra. The Sun/Moon midpoint falls at 0° Virgo. If natal Saturn sits within 1.5° of that point (say, 1° Virgo), the scanner reports the planetary picture Sun/Moon = Saturn.

The Sun/Moon midpoint is nicknamed the "marriage point" in classical Uranian work: it describes the inner partnership between conscious and unconscious self, and by extension the outer partnerships you tend to form. Saturn on that point reads as commitment, weight, structure, restriction, or seriousness in relationships, depending on house and aspect context. Ebertin's short formulation in COSI is "separation of partners; loneliness." Modern readers also see the constructive side: durable partnership, shared responsibility, the long view. That is symbolic relationship testimony, not a verdict on whether a bond will last. For a dedicated reading of just this point by sign and house, use the Sun/Moon midpoint calculator.

The keyword chips on each activation are the starting vocabulary, not the conclusion. Combine the factor themes, weight by orb tightness, and read in the context of the full chart.
