User Reviews for iOptron Polar Scope

location location location #2

I second the 2boldlygo rating - It says this app is good for the itouch, but the itouch doesn't have gps capability (at least not when wifi is turned off). This app should provide the ability to input your lat/long location and it does not.

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.

Awesome

Works perfectly every time! This app get my polar aligned perfectly and keeps the stars pin pointed and without any star trails

No user guidance!!!!

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.

Yep...not good

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...

GREAT APP!!!

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!!

Hopeless App..

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!!

Do not buy - very weak functionality

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.

Don’t use this anymore. Get ds align

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.

Not American English

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.

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.
