Never miss a thing in the night sky

Why does the app ask for my location?
Satellite pass times, true darkness and the weather depend on where you observe. Your location stays on your phone; only a position rounded to about 1 km is sent to the weather services. You can also pick a city manually in the settings, without turning on location.
I'm not getting alerts, why?
Check that notifications for Nuit Claire are allowed in iOS Settings. Alerts are only sent if the sky looks clear where you are: a cloudy night does not trigger an alert, even for a great ISS pass.
Which telescopes are compatible?
Mounts that can be controlled through a SkyFi, Celestron or OnStep Wi-Fi adapter. Your iPhone and the adapter must be on the same Wi-Fi network.
How do I find my log on another device?
Turn on “Sync with iCloud” in the app's settings. Your log, your places, your settings and your nights follow your iCloud account.
How do I invite friends to an observing night?
Create a night in the app, then share the link. Your friends see the invitation in their browser and can open it directly in Nuit Claire.
