Frequently asked questions

CelestiArt is an online editor that draws the real night sky for any date, time and place, and turns it into a personalized, print-ready star map poster. Star maps are sold through the CelestiArt (HumayArt) shop on Etsy.

Every star, constellation, the Moon (with its true phase) and the naked-eye planets are calculated for your exact date, time and coordinates, including time zones, daylight-saving time and precession. Read how it works.
