Robert Hand, Planets in Composite
Definition
Robert Hand, Planets in Composite is an astrological source represented here through cited material on 150 degree rule, houses, midpoints, angles, and aspect priority.

What this work covers
The cited material covers 150 degree rule, houses, midpoints, angles, and aspect priority.
Hand constructs each composite planetary position from the midpoint of the corresponding two natal planets and treats that midpoint as combining the qualities of its two source planets; house construction follows a separate procedure.
Hand treats aspects among the slow outer planets in a composite as generational background unless at least one participating planet is conjunct a composite angle, which makes the aspect personally prominent enough for the source's delineations.
Hand normally selects the midpoint on the shorter arc between a pair of natal planets, but when that shorter arc exceeds 150 degrees he treats the two opposing midpoints as nearly equal in strength and considers both.
