- Dobsonian telescope users planning an observing session
- Worth noticing
- A one-time alignment on a bright star calibrates the phone’s pointing reference; the page says star matching takes about a second.
Field notes
The described setup uses a phone holder aligned with the telescope tube and a one-time tap on a centred bright star. Zenigo then matches stars in a camera image against a catalogue and updates pointing directions as the phone moves. The page also describes target planning by when objects are well placed, eyepiece and finder views, and a logbook; offline use is said to require adding the app to the home screen first.
