Featured moments
Tap a moment to try it.
These are real coordinates, real dates, real night skies. Click any card and the configurator above hydrates with that exact moment so you can see how the renderer feels with different times, latitudes, and styles.
How it works
Designing a star map IS designing a #portal.
The three inputs that build your star map — a name, a place, and a moment — are the same three inputs that mint a #portal on hashtag.org. Drop a portal and the star map for the moment of its minting becomes its cover for free, forever.
Pick your #name
Any single word that means something to you. We check availability live during checkout.
Drop your place
A city, a coffee shop, the cliff where you proposed. We geocode it to exact coordinates.
Lock in the moment
The second you click mint becomes the timestamp baked into your portal AND its star-map cover.
Every #portal you mint ships with a free star map.
Use the configurator above to preview what your portal's cover art will look like. Happy with it? Claim your #name and we generate it at the second you mint, deterministically tied to the lat/lng you pinned and the timestamp of creation. No one else will ever have the same sky.
Why every #portal gets one.
When you create a #portal, we generate the exact night sky above its coordinates at the second you minted it. That image becomes the portal's default cover art forever.
The same astronomical engine that paints the cover paints the poster. What you see on the site is what ships in the frame — pixel-for-pixel, star-for-star.
First kiss. Engagement. The day she was born. Drop the place, drop the moment, pick a style — get a museum-quality print of the sky as it looked, that night.
