The guide inside Celestium
The Arcturus Compass
Arcturus is the brightest star in the northern sky, and one of the oldest wayfinding stars we have. Polynesian navigators sailed under it to find Hawaii. Greek farmers timed harvests by its rising.
That is the work Celestium does with your chart. Not fortune-telling. Wayfinding. Your birth chart is a map of the sky you arrived under, and a map is only useful if you can orient by it.
The Arcturus Compass walks you through it. It welcomes you in, works from your real placements, and shows you one thing to try first on every screen. No jargon wall, no homework.
One guide, across the whole sky.
Where
Your chart mapped onto the whole planet. The places that back you, scored city by city.
When
The transits actually touching your chart, from today out to the year ahead.
Moments
The sky reaches out on the days that matter, and you can keep the ones that land.
Learn
Understand your own chart, at your own pace, with the lineage behind every term.
Find it tonight
You can find Arcturus yourself tonight: follow the arc of the Big Dipper's handle away from the bowl, and the first bright star you reach is it.
