Computing star positions…Assembling your file…Sent to your inbox ✓

Every map is computed from scratch for your date, time and coordinates.

What the map is made of

Not a decorative picture — a computed sky. This is what defines every dot on it.

Size = brightness

A star's size comes from its magnitude on an exponential scale, and stars that draw the constellations are enlarged 1.5×, so the shapes read at a glance.

Colour = spectral class

Star colours follow their real spectral type — from blue-white O stars to warm M ones. A monochrome variant is available too.

Depth of the sky

Distance in parsecs dims the far stars on a logarithmic scale, while the brightest ones — under magnitude 1.5, like Vega or Sirius — get a real glow.

🔭

Real ephemerides

Positions come from professional ephemeris data for any moment between 1900 and 2050 — you can verify the result in any planetarium app.

Your own words

A title and a dedication of your own, constellation lines and names switched on or off — the map says what you want it to say.

Six styles

From midnight gold to celestial blue: pick the one that matches the moment, the preview updates instantly.

Arrives by email

Nothing to wait for: the file lands in your inbox right after the order goes through.

Enormous resolution

A PDF file of about 11800 × 16500 px — zoom all the way in and the stars stay sharp.

Find the words for your sky

Add a caption that makes the star map personal. Here are a few ideas — or write something that's all yours.

  • "Under these stars I chose you"
  • "Our night — February 14, 2021"
  • "On this day you came into the world"
  • "The sky above the city where it all began"
  • "We said 'I do' under these constellations"
  • "The stars remember our first kiss"

Frequently asked questions

How accurate is the star map?+

We compute the real positions of stars and constellations by the date, time and coordinates of the chosen place — it's real astronomy, not a decorative picture.

What do I get after paying?+

A high-resolution digital star map as a PDF file, about 11800 × 16500 px, arrives in your inbox as an email attachment.

Do I need to know the exact time of the event?+

It helps, but it's not required. If the time is unknown, leave the default value — it barely affects the overall picture of the sky.
