Polar Scope Align Pro Watch

Daytime Alignment now lets you calibrate by aiming your camera at the sun, a planet or a star. More accurate than the phone compass, immune to magnetic interference.

Polar Scope Align Pro is a complete toolkit for amateur astronomers: accurate polar alignment, deep-sky observing, astro weather, push-to/manual GoTo, iOptron mount WiFi control, widgets and more. All features and updates are free forever. Optional in-app purchases are just tips to support development.

POLAR ALIGNMENT • Calculates Polaris or σ Octantis position for 30+ reticle types: iOptron, Astro-Physics, Takahashi, Skywatcher, Vixen, Celestron, Orion, Astrotrac and others* • Atmospheric refraction correction for accuracy at any latitude • Works with or without a polar scope

ALIGNMENT WITHOUT A POLAR SCOPE • Daytime / No Polar Scope Alignment: works day and night with just your phone's gyro • Camera Azimuth Calibration: use sun/moon/stars to calibrate gyro and align accurately without a compass, immune to magnetic interference • Laser / Hop Align: nighttime alignment for maximum accuracy with a laser or a scope with no view of Polaris • Live sky map guides you to the celestial pole in real time

PUSH TO (MANUAL GOTO) • Attach your phone to any scope and convert it to manual/push GoTo • Select from a large database and use direct push or more accurate hop-to mode
