Cosmobiology / midpoint astrology in the lineage of Reinhold Ebertin's The Combination of Stellar Influences (1940) and Alfred Witte's Hamburg School — the half-sum method on the 90° dial. Where a natal chart asks where the planets are, cosmobiology asks where their MIDPOINTS fall and what stands on them: a third factor on the midpoint of two others forms a 'planetary picture' C = A/B, read as a single combined dynamic (e.g. Mars = Saturn/Pluto). From the birth moment it builds the 13 classical factors (Sun–Pluto, North Node, Ascendant, Midheaven) and their 78 midpoints, then finds every picture at an 8th-harmonic HARD aspect (0°/45°/90°/135°/180°) within a graduated orb, organised into midpoint trees by apex; it highlights the Sun/Moon midpoint (the 'point of personal integration') and flags Aries-Point/world-point contacts. Hard aspects only; Chiron, asteroids and the hypothetical trans-Neptunians are deliberately excluded. The half-sum arithmetic is locked against published worked examples and shares the same ephemeris as our natal engine; the midpoint pictures are a symbolic language for reflection, not a validated predictor.
