An American friend once visited us with a Celestron Nexstar 5 and in the Southern Hemisphere, he discovered the following:
- ‘Scope must be pointing N
- Base must be level
- Enter Lat & Long
- Enter Local time
- Select Time Zone 14 for Australia.
This was the original Nexstar 5 model and the date was around 2001, so I’m not sure if the controller, software or procedure has changed since then.
