What the digital download includes →What a star map can—and cannot—show
A star map is a calculated representation of the sky for selected inputs. It is not a photograph, a weather record or an astrology reading. An unknown time is not an exact birth instant.
How our sky works →A note to give with a digital gift
A date and a few words can make the handover personal. Choose a note, replace the placeholders and print or send it yourself.
These are original examples for you to adapt. A note is not a gift voucher, an order confirmation or a promise of a delivery date.
