Personalised star map poster

Right on the product page, with no account needed: search for the place (a town or an address), enter the date and time, pick one of the ten styles, then write the title and the dedication. The preview redraws with every change, and designing costs nothing: you only pay when you order — €8.90 for the print-ready file, from €19.90 for a printed A4 poster.

€8.90 for the print-ready file you print yourself (all five sizes, as PDF and 300 dpi PNG), €19.90 for a printed A4 poster, and up to €69.90 for the largest size, 70 × 100; the frame, available on A4 and 30 × 40, is added to the print price. Shipping €3.90 in France and the European Union, free from €49. The file has no delivery charge.

Three things are worth checking before you order, wherever you buy. The stars must be calculated for the place, date and time: change the time in the preview and the sky should turn — if it doesn't, it's a decorative starry background. The time must be local time, with summer time taken into account. And the preview must be exactly what gets printed. At Poster de Blonde, the stars visible to the naked eye, down to magnitude 6, come from the Hipparcos catalogue — 5,044 across the whole sky — and the print file is made by the same page as the preview, with your details.

In France: it is printed to order in our workshop in the Aveyron, whatever the size, then checked before it ships. It leaves within 48 hours; allow a week for France and ten days elsewhere in the EU. For a last-minute gift, the print-ready file arrives by download link the same day.

The stars visible to the naked eye (down to magnitude 6) above the place, at the chosen date and time, with the constellations. North is at the top, the horizon at the edge of the disc, like a planisphere.

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.

Those of the moment you want to keep: a birth, a first meeting, a wedding. The time is the local time at the place; if you don’t know it, pick nightfall, around 10 pm.

A4, 30 × 40, 40 × 60, 50 × 70 and 70 × 100 cm: standard frame sizes, easy to find in supermarkets and homeware shops. Optional wooden frame on the A4 and 30 × 40, in black, white or natural, with acrylic glass; the larger sizes ship rolled, to frame at home.

250 g/m² matte paper, lightfast pigment inks. Printed to order in our workshop in Aveyron, whatever the size. Shipped rolled, in a sturdy long cardboard box; the A4 travels flat, in a stiff card envelope.

Yes. The print-ready file contains all five sizes, each as a PDF and as a 300 dpi PNG — ten files in all, by a download link sent after payment, to print wherever you like.

Printed within 48 hours, then delivered to your home or a pickup point — home delivery only for the 50 × 70 and 70 × 100. The download link for the print-ready file is sent the same day.
