iOptron Optical Polar Scope

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.

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.
