Spherical Geometry Alexey Borealis

An essential concept in primary directions is the ascension difference. Learn how to calculate this value. This article is for prof. astrologers.

Spherical Geometry Alexey Borealis

Astrologers must convert zodiacal coordinates to ecliptic coordinates and vice versa when calculating primary directions. Let's derive these formulas.

Spherical Geometry Alexey Borealis

Spherical triangle equations are the foundation of mathematical work for an astrologer-forecaster. We will derive these functional equations here.

Spherical Geometry Alexey Borealis

These equations express the coordinates of the planet in various spherical coordinates and provide a basis for calculating primary directions.

These basic formulas are needed to understand the subsequent calculations of the primary directorates. Read it if you use this method.

House Systems Alexey Borealis

The house cusp in the Regiomontanus system is the intersection of the major circle of position with the zodiacal plane. Here are the formulas.

House Systems Alexey Borealis

Morinus considered this system the most accurate prediction system, and we agree. Find out what the Regiomontanus house system looks like in space
