I
Your Sun — the self
The sign and house of your Sun is the spine of the chart: what you are here to become, and the room of life you become it in.
Premium report · The blueprint
Your birth chart, readas one long letter about who you are.
Your natal chart is the sky frozen at the minute you were born — every planet, house, and angle in the exact place it stood. Luxtra computes all of it from your birth moment with the Swiss Ephemeris: a chart born 14 March 1990, 04:25 in San Francisco carries a Pisces Sun in the 9th house, a Scorpio Moon, and a Sagittarius Ascendant.

Everything the sky was doing the moment you arrived — read back to you. Your Sun, your Moon, your rising sign, and the houses they fell into. The chart assembles star by star, computed from your real birth data. This is the blueprint everything else is built on.
What it reveals
The substance of your reading.
The three placements everyone starts with — each computed, each a thread.
II
Your Moon — the inner weather
The Moon is how you feel safe, what you reach for at night, the need underneath the personality. It moves a degree every two hours, so the minute matters.
III
Your Rising — the mask
The Ascendant is the sign that was climbing the horizon as you were born — the face you lead with, and the lens the whole chart is read through.
From a sample reading
Sun in the 9th house
You were born facing the horizon. The 9th is the house of the long journey — the foreign country, the higher idea, the belief worth crossing a border for — and your Sun lives there, which means you will never quite be at home in the town you were raised in. This is not restlessness. It is design.

Frequently asked
Master Natal, in plain answers.
What is a natal chart?
A natal chart, or birth chart, is a map of the sky at the exact moment and place you were born. It shows where each planet sat, divided into twelve houses, and the angles they make to one another — the foundation of every other reading in astrology.
Do I need my exact birth time for a birth chart?
For the Sun sign and most planets, no. But the Moon, the Ascendant, and all twelve house positions depend on the time — the Ascendant moves about a degree every four minutes. Luxtra computes a solar chart without a time and tells you which parts depend on it.
Which house system does Luxtra use?
Luxtra supports eleven house systems — Placidus, Whole Sign, Koch, Equal, and more — and defaults to Placidus. You can switch systems and recompute instantly.
