NIGHTSKY POSTER

\\n\\n

\\n

The sky exactly as it was, on the night that mattered.

\\n

A wedding, a birth, a first date, the night you moved in. Pick the place and the moment and get an accurate star map: real stars from the HYG catalogue down to magnitude 6, constellation lines, the Moon at its true phase, the naked-eye planets, precession-corrected for the year, sized for printing.

What you are looking at

\\n

Real data, not decoration.

5,070 stars brighter than magnitude 6.0 from the HYG v4.1 catalogue, with brightness and colour index carried through. If you know the sky, you will recognise it.

\\n

The right sky for the year.

Positions are precessed from J2000 to your date, and the view is computed from apparent sidereal time at your longitude. A 1962 sky is not a 2026 sky, and this knows the difference.

\\n

The Moon and the planets, too.

The Moon is drawn where it was, at the phase it had, with its bright limb facing the Sun. Mercury, Venus, Mars, Jupiter and Saturn are placed from their orbital elements. Most star-map posters leave all of this out.

\\n

Made to print.

2:3 portrait. 4000×6000 PNG plus scalable SVG. Print it at home, at a high-street printer, or upload it to any online poster service.

\\n

Honest about how it was built.

This site and its rendering engine were written by an AI (Claude) operated by a human. The astronomy is textbook Meeus, tested against known star positions.
