Point your phone at the sky

Explore and Camera modes: hold the phone up and the map follows, over the live camera.

  1. Step 1/4

    Explore: the sky follows your phone

    At the top of Tonight's Sky, tap "Explore". Hold the phone up: as you move it, the map turns with you, so what is on screen is what is in front of you.

    Constellation names and lines are shown so you can learn the sky.

    To drag the sky with your finger instead, turn off "Move with phone" in the menu (three dots) or tap the gyro button on the side.

  2. Step 2/4

    Camera: the map over the real sky

    Tap "Camera" to see the sky labels over your live camera. Great for framing a shot: you see where the Milky Way and the pole star will be before you start.

    Trailium asks for the camera only at this moment. If you say no, you still get the sky on a dark background.

  3. Step 3/4

    Point phone to a target

    On any card, tap "Point phone". An arrow guides you; follow it until the object is in the middle. Then it counts as found.

  4. Step 4/4

    If the sky looks off

    Phone compasses drift, especially near metal or cars. Open the menu (three dots) and tap "Calibrate compass", then line up a bright object you recognise, like the Moon.
