Midpoint Explorer
Between any two planets lies a degree that blends them, and when a third planet stands on that degree the blend becomes a working theme of the chart. Midpoints are the precision tool of the Ebertin school: less poetic than aspects, often more specific. This lab computes all of yours and surfaces the activated ones.
Load a chart to compute every planetary midpoint and find which ones are activated by a third planet, directly or on the 45° dial.
How to use the Midpoint Explorer
›The idea
A midpoint is the degree halfway between two planets, and cosmobiology reads it as their blended agenda: Sun/Moon is the marriage of aim and need, Mars/Saturn is effort against resistance. On its own a midpoint is latent. It matters when a third planet stands on it.
›Direct and dial activations
A direct activation means a planet conjunct or opposite the midpoint within 1.5 degrees: the strongest case. Dial activations sit at any multiple of 45 degrees within 1 degree, the classical 8th-harmonic dial used by Ebertin's school. Direct hits are listed first; treat dial hits as secondary evidence.
›How to read an activation
Name the blend first (the two midpoint planets), then let the activating planet describe how it expresses. Moon/Venus activated by Saturn reads as tenderness expressed through duty and restraint. Start with activations involving your Sun, Moon, or angles: those reach consciousness fastest.
