Pegasus is famous for the Great Square, a large pattern that anchors many autumn sky searches.

Quick facts

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

Start with the brightest nearby objects, then compare Pegasus 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.

Pegasus is best seen during autumn evenings, often high enough to act as a useful starting pattern.

Look for four stars forming a large, mostly empty square. It is larger than many beginners expect.

Once the square is aligned in AR, follow the overlay eastward to find the Andromeda star chain.
