Quick facts

Use these cues first, then confirm the pattern in the AR viewer.

Start with the brightest nearby objects, then compare Leo with the AR overlay.

Altitude and direction change with latitude, longitude, date, and time.

If the phone compass drifts, adjust the heading controls until a known star pattern lines up.

Leo is well placed in evening skies during spring. Regulus is the bright star near the base of the Sickle.

Find the backward question mark shape first, then follow the body eastward toward Denebola.

Use AR to confirm the Sickle and body line, especially when only the brightest stars are visible from a city.

Short answers for common skywatching questions before opening the AR viewer.
