Description
Polar Scope Align is a free, ad-supported polar alignment app for iPhone and iPad.
It calculates the position of Polaris or σ Octantis in your polar scope reticle for your location, date and time, helping you get a quick and accurate polar alignment with an equatorial mount.
POLAR SCOPE ALIGNMENT
Accurate Polaris and Sigma Octantis position for your date and location
Atmospheric refraction correction for better accuracy, especially at lower latitudes - readings may differ slightly from simpler apps that skip this correction, but will agree with precise sources (USNO, scientific software)
Automatic time and location
Manual location support
Reticle centering-error measurement and correction
Zero-position help for common Celestron / Sky-Watcher / Orion style reticles
Full red night-mode interface
