A little astronomy, made personal
About Real Star Map
Real Star Map turns a meaningful date into something you can see and keep. Make a map of the stars above a place and moment, or discover the Moon’s phase on a birthday. The tools are free to use, with no account or email required.
Calculated skies, explained openly
Our tools use Astronomy Engine and published astronomical catalogs. Our Moon illustration uses NASA imagery. We explain the sources, projection and limits on the accuracy page, so you can compare results with independent astronomy tools.

Star maps download as high-resolution PNGs for printing, while square and story formats make sharing easier. The birthday Moon calculator also exports free cards. Files are generated on your device; we do not operate a hosted gallery of personal designs.
Real Star Map currently offers digital files. It does not sell or ship physical prints. You can print your file yourself or take it to a print shop.
Your choices matter
Optional analytics, when enabled, helps us learn which tools are useful. It excludes your chosen dates, locations and personal messages. You can decline it and keep using every tool. Read our privacy notice.
