The natal instrument
Every placement, aspect, house cusp and dignity, computed from a real ephemeris and drawn as a chart you can read at a glance or take apart piece by piece.
Opening October 2026
The sky keeps its own hours
Opened at the eclipse

An observatory for one sky and one life. The chart is read the way a forecast is read: conditions, not verdicts. What the sky is doing, and what you might do about it.
The beta observatory is open for testing. Nothing is charged yet; paid tiers begin at launch.
The eclipse window runs 9 to 12 August, when the sky puts on its rarest showing over Europe.
Open what you want to read
Every placement, aspect, house cusp and dignity, computed from a real ephemeris and drawn as a chart you can read at a glance or take apart piece by piece.
Transits are reported as conditions with a beginning and an end. A hard aspect is a headwind to plan around, never a sentence handed down.
Tropical and sidereal are held side by side, with whole-sign and Placidus houses available, so a reading is never hostage to one convention.
A calendar view that marks the windows worth using in the weeks ahead, tied to your own chart rather than a generic daily horoscope.
Synastry and composite work for partners, family and colleagues, written as a description of the weave rather than a compatibility score.
Readings are saved, dated and exportable. Nothing you were told last spring quietly disappears when the model behind it changes.
One payment, no subscription
$2.99
A single door, opened once. It answers a question people have asked of their own charts for four hundred years, with the historical record attached rather than a costume version of it. The answer is about temperament and inheritance, and it is written to be read aloud.
There is no free tier and there is no free forever. What there is: six placements, computed properly and given without charge, so you can see the quality of the work before deciding whether to pay for the rest.

Positions are computed from a standard ephemeris, not generated. The written interpretation around those positions is produced with the assistance of a large language model, working from an edited body of traditional and modern astrological material. Every reading is machine-assisted, and it is labelled as such wherever it appears.
Almagestral is for reflection and entertainment. It is not medical, psychological, legal or financial advice, and it does not replace a qualified professional. If something in your life needs a doctor, a lawyer or a therapist, please go to one. Nothing here predicts illness, death or ruin, and nothing here is written to frighten you into paying.
Birth time and place are stored to compute your chart and for nothing else. They are never sold, never brokered to advertisers, and never used to train a model. You can export everything held about you, and deleting your account deletes the data with it.
A subscription buys access to the instrument and the readings, billed monthly or yearly, cancellable at any time from inside the account. Prices shown here are the prices charged at opening. If they change later, existing subscribers keep the rate they signed at.
Almagestral is an instrument, not a replacement for a reader. A month after opening, a directory of working astrologers goes live inside the observatory, so a subscriber who wants a person rather than a document can find one.
