What Is a Custom Star Map?
A custom star map is a precise representation of the night sky as it appeared from a specific location, at an exact date and time. Every star, every constellation is positioned exactly where it was during your chosen moment — making it a truly unique piece of art.
Whether it's the night you got married, the day your child was born, or the evening of a first date, a star map captures that moment in the stars forever.
How Are Star Maps Created?
At OwnStarMap, we use the HYG star catalog — a database of over 100,000 stars with verified astronomical data from the Hipparcos, Yale, and Gliese catalogs. Our calculations are based on standard IAU (International Astronomical Union) algorithms for:
- Sidereal time calculation for your exact moment
- Coordinate conversion from celestial to viewing coordinates
- Stereographic projection to map the celestial sphere onto a flat surface
The result? A scientifically accurate representation of the sky showing 8,921 visible stars (magnitude ≤ 6.5), complete with constellation lines and labels.
