설명
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.
새로운 소식
Added support for new iOS and iPadOS devices. Now requires iOS 18. Minor improvments.

Shows polar position that is not accurate. Its position varies at different times of day even if you are standing on the same position/location.
This one is only for ioptron with very limited functionality. No new features after all these years. I use DS align now, support many many other mounts polar scope and so much more functionality. Even has a iwatch version.
It tells you where Polaris is located for your current time and location. But with no options or way to configure the display (other than English / Chinese). Other apps do this as well but with plenty of options for customization. It might be OK if it were free, but it is dismal at $1.99.
Purchased and no instructions or troubleshooting guide. Couldn’t even figure out how to contact the developer. I can’t even give it a rating...I guess I’ll have to buy ZWO...
The elevation is in metric not much help in the USA. If it can be converted to Chinese why not USA measurements? I’m not knocking metric but I’ve spent 60 years using feet ,miles and Fahrenheit. So only half of this app is of any use for me. It’s only good for alignment I should have paid better attention and not assumed it was for the US market. I can use it but I won’t have a clue about my elevation.
I feel ripped-off! I’m in the southern hemisphere and can’t figure out how to use the darn thing to find sigma-oct! Piece of junk!!
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. ;) Thanks!!
Works perfectly every time! This app get my polar aligned perfectly and keeps the stars pin pointed and without any star trails
First, the position of Polaris is 5 arcminutes too low. (If the app says 39', the actual position is 44'.) Second, there are no settings to change meters to feet or degrees C to degrees F. I intend to get a refund.
You pay for it and then you find out that there is no guidance from iOptron on how to use it or read from the circle.
