Preferences… - Open the application preferences window.

File menu:

Configuration Wizard… - Set the eclipse, observer’s location and photography equipment to generate a basic camera script.
New Script (⌘N) - Create a new script.
Open Script… (⌘O) - Open a script file so you can modify it.

Close (⌘W) - Close the frontmost window.

Observer menu:

Location… (⌥⌘L) - View or modify latitude, longitude and altitude in the Photographer Location dialog.
Update Location from GPS (⌘6) - If a GPS is connected, the observer’s coordinates are updated, then the local circumstances and event times are recalculated, and finally any running script is reloaded to make the event time changes take effect. Enabled only when the GPS is connected and has a position fix.
GPS Position Tracking - If a GPS is connected, the position of the moving observer can be tracked and the eclipse circumstances recomputed at a frequency tied to the speed of the mean of transport used (seaship, airplane or spaceship). Enabled only when the GPS is connected and has a position fix.
The GPS track log file named GPS_Track_Log.txt is created inside the Solar Eclipse Maestro folder located in the current user’s Documents folder.
- Turned Off - There will be no GPS tracking.
- Stationary - Track the GPS position every 2 minutes.
- Shipborne - Track the GPS position every 30 seconds.
- Airborne (Slow) - Track the GPS position every 5 seconds.
- Airborne (Fast) - Track the GPS position every 2 seconds.

Current Time - The application clock matches the Mac’s clock (except for the optional clock error correction), this is "real time".
Simulated Time… (⌥⌘T) - Use this to test your eclipse scripts. It sets the software to an arbitrary date and time without messing up the Mac’s clock.
Simulated First Contact - Use this to test your eclipse scripts starting forty seconds before first contact. It sets the software to an arbitrary time without messing up the Mac’s clock.
Simulated Second Contact - Use this to test your eclipse scripts starting forty seconds before second contact. It sets the software to an arbitrary time without messing up the Mac’s clock.
Simulated Third Contact - Use this to test your eclipse scripts starting forty seconds before third contact. It sets the software to an arbitrary time without messing up the Mac’s clock.
Simulated Fourth Contact - Use this to test your eclipse scripts starting forty seconds before fourth contact. It sets the software to an arbitrary time without messing up the Mac’s clock.
Simulated Sunrise - Use this to set the time to forty seconds before sunrise on eclipse day. It sets the software to an arbitrary time without messing up the Mac’s clock.
Simulated Sunset - Use this to set the time to forty seconds before sunset on eclipse day. It sets the software to an arbitrary time without messing up the Mac’s clock.
Adjust Event Times… (⌘7) - View/edit event times for sunrise, sunset, first through fourth contacts, and maximum eclipse in the Event Times Override dialog. When a script is already loaded, it is automatically reloaded to update the script actions. If you wish to automatically override computed times, write down the event times in the script, and then make sure to never select Observer’s Location… or to change Refraction Correction or Lunar Limb Profile Correction as touching any of these will wipe out your override (until you reload the script).
