Personalised full-page star map poster — the sky of your date

The star map of the night it all began, across the whole sheet: you give the place, date and time, and the poster shows the exact stars of that evening in a large circle, with a title (“The day we met”), a line of your choice and the coordinates of the place.

Azure, the navy night, is closest to a classic star map and suits almost everyone; burgundy and copper are warmer, forest is calmer, violet more dreamy. You can change mood at any time, and the preview follows.

The sky above the place, on the date and at the time you choose, in a large lighter circle set on a night that covers the whole sheet: the stars visible to the naked eye (down to magnitude 6), the constellations drawn in, the Milky Way where it really was, and two fine rings around the circle. Below, your title, a line of text, the city with the date, and the coordinates.

The stars and constellations in the circle are calculated for your place, date and time from the Hipparcos catalogue. The night background around it — its gradient, its coloured clouds, its dust of stars — is a backdrop drawn by computer from the date and time, so the same sky always gives the same background.

Five: azure (a navy night with a lighter blue circle, closest to a classic star map), burgundy, forest, violet and copper. Each has its circle, lighter than the night, its stars and its own ring design. You can change mood at any time and the preview follows.

The title fits on one line — “The day we met”, two first names, “The night we married” — and the line below, up to 90 characters, is optional: you can clear it and the poster keeps its title, date, place and coordinates.

The moment you want to keep: a first meeting, a proposal, a wedding, a birth. The time is the local time at the place; if you do not know it, pick nightfall, around 10 pm.

Positions are computed from the Hipparcos catalogue, precession included, at the local time of the place (daylight saving accounted for). Accuracy is around a tenth of a degree.
