Description

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.). The overall accuracy of the algorithm has reached sub 0.1 arc-seconds now.

The app now using a 10 minute marker reticle, the same reticle used in the polar scope of iOptron(R) telescope mount since 2014.

A must have for iOptron(R) SkyGuider Pro, iOptron(R) SkyTracker Pro, SkyGuider and SkyTracker users!
Also very helpful for any iOptron(R) telescope mount owners. It may also be used with other brand telescope/camera mounts with similar polar scope reticle.

No human interaction required when iOS devices can using location service normally.
iOS users can manually enter the location when location service is unavailable.

Version 8.12

Now display 2 more decimal digits in longitude and latitude.

Only works if GPS is online.

This app will not let you enter a position manually. It will work only with the position determined by the iOS device. So if this position is not right, it does not work.

Works Well

Thanks for continuing to support this app and the tracker.

Love SkyTracker, but the app could be improve...

Just love the SkyTracker, and the app is very usefull so to acurately polar align the mount, but you should add a feature that would simply memorise the locations we used... And -or be able to manually enter the coordinates of our actual location. Would be usefull for those with a non 3G iPad for example... Other than that, this combinaison is best way to start in astrphotography...
