About this instrument

The stars that stood over your birthplace at your birth moment, drawn as a plate, next to the same patch of sky tonight. What has moved, and what has not.

Occasion

Midday unless you know the hour — birth certificates usually record it.

Amsterdam, Netherlands

The Sun was above the horizon at that moment. These stars were there, but nobody could have seen them.

Developing the plate…

How many stars

A sky you could pick the shapes out of on a good night. The default.

Which way you were facing

A chart like this is meant to be held up and turned to match the sky. Put the direction you were looking at the top and the compass marks turn with it.

Positions are true, without refraction, as star charts are drawn. East is on the left: you are looking up, not down at a map.

Stars to magnitude 6.5 — everything the unaided eye can see from a dark place.
