What is a custom star map?
A Sigastra custom star map is a print of the real night sky above one place at one moment. We compute the positions of 5,044 stars, the planets and the Moon for your date, time and coordinates, draw the 88 constellations and add your names and a line of your own. You receive a 300 dpi print-ready PNG file by download and email within minutes, sharp up to 30×40 in (75×100 cm).

Questions about the custom star map
Is it really the sky of that night?
Yes. Every star, planet and the Moon is placed for the exact place and minute you choose, from the Yale Bright Star Catalogue and the HYG database, with planet positions from the same models observatories use. Change the city or the hour in the editor and you can watch the sky turn.
What if I don't know the exact time?
The sky turns about 15 degrees an hour, so the evening you remember is close enough for most people. If you leave the time as it is, we use 9 pm local time.
What do I receive?
A print-ready 300 dpi PNG file of your star map, by download and by email, usually within a few minutes of paying. The files are yours to print as often as you like.
Which languages can the print be in?
Seventeen languages and scripts, including Spanish, German, French, Japanese, Arabic and Serbian. Dates, constellation names and every label follow the language; names and your own words stay exactly as you type them.
Can I have it printed and framed?
Yes. After checkout you get links to print services in your own country (for example WhiteWall, Framebridge, Mpix or myposter). You upload the file there, choose the paper, size and frame, and they deliver it to your door. Printing locally means no customs, no transit damage and fast delivery. You can also take the file to any print shop you like.
What size can I print?
The file is 9,000 × 12,000 px: a true 300 dpi at 30×40 in (75×100 cm), so every smaller size is sharp too. The print guide lists every size for each shape.
