HOW IT WORKS
Alignment Made
Alignment Made
Simple
Three easy steps to achieve professional-grade polar alignment for your telescope mount.
STEP 01
Get Your Location
Enable GPS to allow AstroLock to calculate your exact position, magnetic declination, and visible celestial pole.
STEP 02
Calibrate Sensors
Perform a simple figure-8 motion to calibrate the magnetometer and gyroscope for maximum accuracy.
STEP 03
Align & Observe
Follow the real-time HUD guidance to align your equatorial mount with pinpoint precision.
Average alignment time: Under 5 minutes
