Read moreFrequently asked questions
Short answers for common skywatching questions before opening the AR viewer.
Why do constellations change through the year?
Earth orbits the Sun, so the nighttime side of Earth faces different star fields in different seasons.
Can I find constellations in a city?
Bright patterns such as Orion, the Big Dipper, Cassiopeia, Leo, and Cygnus can often be recognized, but faint stars may be hidden by light pollution.
Why does the AR viewer include manual alignment?
Phone compasses can drift. Manual adjustment lets you line up the overlay with a known bright pattern before exploring fainter constellations.
