A field guide to your sky

Learn to read your birth chart

Start with a question. Each guide explains one part of a birth chart and how it connects to the whole.

Start here

Sun, Moon, and rising.

Three starting points. One chart. Get to know your Big Three.

Understand the different jobs of your Big Three and why birth time changes what a calculator can tell you.

Read a chart wheel in a practical order: horizon, signs, houses, planets, then aspects, with a calculated synthetic example.

What an unknown or approximate birth time supports, what can change, and how to find a better record without guessing.

A practical map of the ten bodies in a LunarOtter chart, from personal planets to slower shared placements.

Understand conjunctions, oppositions, squares, trines, and sextiles with a worked angle example and LunarOtter’s fixed orbs.

What changes between Whole Sign and Placidus charts, what stays fixed, and why LunarOtter uses one documented house system.

Understand the MC as a calculated angle, its traditional public-life themes, and why it is separate from the tenth Whole Sign house.

Separate apparent backward motion from its astrological interpretation, and learn how a natal retrograde flag is calculated.

What your Sun, Moon, or rising sign means, one sign at a time, with a fictional worked example on every page.
