常見問題
Where do the eclipse dates come from?
They're worked out on your device with the open-source Astronomy Engine. We check every eclipse from 2021 to 2030 against the published tables by Fred Espenak.
Does it use my location?
Only if you ask it to. Your place stays on this device and is used to work out what you can see. You can also type it in, or use the app without one.
Why don't the constellation lines look like the ones I know?
Each figure is the shortest route through the constellation's brightest stars, worked out by the app. It shows which stars are there, not the traditional picture.
Is it safe to watch a solar eclipse?
Only with certified eclipse glasses or a proper solar filter, except during the brief total phase. The app says so on every solar eclipse.
Can I use it offline?
Yes. Once installed, everything works without a connection, because it's all worked out on your device.
Astronomy是免費的嗎？
是的。免費使用，免註冊，也不用安裝任何東西。
