Constellation guides

Each page answers what the constellation is, when it is visible, and how to find it with AR.

How to choose a constellation guide

Begin with constellations that have bright anchor stars and simple shapes before moving to larger or fainter patterns.

Orion, Cassiopeia, the Big Dipper, Leo, Cygnus, and Scorpius are useful because their brightest stars can survive moderate light pollution.

Each guide explains what to look for first, which season is best, and how to use AR as a confirmation tool after you recognize a real pattern.

Why constellation pages are not all identical

A good constellation page should explain the specific anchor stars, season, shape, and nearby sky region for that pattern.

This avoids thin programmatic content. The goal is to answer real observing questions that a beginner would ask outside.

Frequently 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.
