Solar safety: never look directly at the Sun. Filter the camera lenses during partial phases.

Requesting camera and orientation access…

Refine alignment with the Sun requires a visible Sun and a proper solar filter

Calibrate with the visible Sun<br>Camera width 60°

If the Sun is not visible, camera width can be adjusted manually, but there is no reliable visual reference. The last calibrated camera width is remembered; compass correction is not reused because it changes with the magnetic environment.

Done

Only continue with a visible Sun and a fitted solar filter<br>Securely cover the phone’s active camera lenses with a suitable solar filter. Never look directly at the Sun without certified solar viewing protection. Doing this without a filter may permanently damage your phone and/or eyes. The phone screen does not protect your eyes.
