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 now manually enter the location when location service is unavailable.
NOTE: Since 2017/03/03, This app has the identical result as iOptron 8407, 8408 hand controller and iOptron Commander 5.4.
Added support for iPad Air 3rd generation and iPad mini 5th generation.
Ratings and Reviews
If I haven’t used it for awhile I forget how great an app it really is. Simple, accurate, and easy. That’s what I want when out in the dark. ;)
Works perfectly every time! This app get my polar aligned perfectly and keeps the stars pin pointed and without any star trails
Very nice app for iOtpron EQ mount owners, it would be nicer is the date actually worked correctly?
The date is a year off...the month is off by a month..and the day is off. The actual info on Polaris seems to be correct.
