A personalized star map is commemorative artwork generated from a chosen date, local time and location. OwnStarMap rotates fixed coordinates from an HYG-derived catalogue, filters the geometric horizon and projects the remaining star layer. It does not replace a professional planetarium or astrometry tool.

The current renderer uses fixed catalogue coordinates, Greenwich mean sidereal time, observer-based horizon filtering and stereographic projection. It does not model the Sun, Moon, planets, weather, terrain, atmospheric refraction, precession or individual stellar motion.

Star maps are perfect for births, weddings, anniversaries, first dates, engagements, or any important moment. It's a unique and personal gift that captures the beauty of the sky at a precise moment.

We offer a digital download ($14.00) and printed posters in 4 sizes: US Letter, A2, 16×20 inches and 18×24 inches. All files are in high resolution.

The editor accepts a four-digit date and provides a preview. Historical dates have additional epoch and civil-time limitations, so use a professional planetarium when a research-grade reconstruction matters.

You can preview the design free. The current amount and presentation currency depend on the selected product and market; the final amount and currency are shown before payment confirmation. The digital deliverable is a PDF in your selected design format.

OwnStarMap uses an HYG-derived catalogue containing 8,921 records. The renderer skips Sol, filters records below the geometric horizon and applies the selected shape boundary. It uses fixed catalogue coordinates, local sidereal time and stereographic projection; the published accuracy guide explains the limitations.

A personalized star map uses catalogue data to create commemorative artwork for a chosen moment. 'Name a star' services offer symbolic naming with no scientific recognition; the International Astronomical Union does not recognize commercial star naming. Both products are gifts, but they make different claims.
