* A device with a magnetometer and gyroscope are required to measure your local horizon. If your device does not have these hardware features, you can still set the local horizon in Observer Pro to a constant value or import a local horizon data file after measuring it with a friend's device, your telescope mount, or just a simple compass and protractor!
