Midpoints and Planetary Pictures
Midpoints Astrology explains circular half-sums, opposite axes, A/B=C planetary pictures, dials, a worked example, and method limits.
Overview
Midpoint methods calculate the halfway position between two factors, while planetary pictures and 90° dials apply additional symmetry rules from Uranian and Cosmobiology schools. The page separates calculation from interpretation and keeps this worked result conditional: wrapped Sun/Moon midpoint is 0°, and Mars at 1° forms the declared midpoint picture. A midpoint is the circular half-sum between two zodiacal longitudes and has two opposite solutions. A planetary picture records a third factor contacting that axis, often as A/B=C. Direct midpoints, midpoint trees, 90-degree or 45-degree dials, and Cosmobiology or Uranian conventions are related but not interchangeable methods. Verification follows this declared method: Calculate both 0–360° midpoint solutions, declare the dial and modulus, then test whether a third factor contacts the selected midpoint within its own narrow orb.

Definition and exact scope
midpoint methods calculate the halfway position between two factors, while planetary pictures and 90° dials apply additional symmetry rules from Uranian and Cosmobiology schools
Calculation or decision rule
calculate both 0–360° midpoint solutions, declare the dial and modulus, then test whether a third factor contacts the selected midpoint within its own narrow orb. Convert both factors to longitudes from 0 to 360 degrees, calculate the circular half-sum and its opposite axis, then measure the third factor to both solutions under a narrow, declared orb. Record whether a 360-, 90-, or 45-degree modulus is used and whether the contact is natal, transit, progression, or solar arc. Keep Witte, Hamburg School, Ebertin, Cosmobiology, and modern software defaults distinct.
Worked case and illustrative near miss
☉ at 350° and ☽ at 10°; 360° midpoint method; ♂ at 1°; orb cap 1.5°. wrapped Sun/Moon midpoint is 0°, and Mars at 1° forms the declared midpoint picture.
Illustrative near miss: A naive arithmetic midpoint of 180° ignores the 0° crossing and produces the opposite point.
School and variant boundary
Dial, modulus, midpoint equation, point catalog, notation, and orb belong to a named Uranian or Cosmobiology lineage.
Product, safety, and verification boundary
OpenFate presents Midpoints and Planetary Pictures as a sourced knowledge method and does not claim a dedicated calculator or generated reading for it. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Midpoints and Planetary Pictures cannot diagnose a person, remove consent, or guarantee an event.
