iOptron Polar Scope!

This is an app to show the position of the Pole Star (Polaris in Northern Hemisphere, or Sigma Octantis in Southern Hemisphere) in the polar scope of all the iOptron(R) telescope/camera mounts. The app uses the best algorithm to calculate the position of Pole Star: The algorithm calculates 3D space motion of the Pole Star itself, precession, temperature and barometric pressure corrected atmospheric refraction, nutation, parallax, aberration, and etc.). NOTE: Since 2017/03/03, This app has the identical result as iOptron 8407, 8408 hand controller and iOptron Commander 5.4.
