Tool Rich Environment

Love the various tools included in the app. Up front I expected this to be used just for polar alignment to support an older Celestron Polar finder. Instead…I find myself using the calculator section with various eyepiece calculators. Then there is the push-to capability that has numerous catalogs like Messier, Caldwell, Herschel, etc. Any possibility of designing this app to be able to be used in conjunction with other apps like Stellarium? It would be cool if the push-to reticle showed up on the Stellarium screen.

Worked once

Was fantastic, one time. Since buying the app, the main polar alignment window is always permanently frozen. The star hop function works erc. But the main polar alignment screen does not. Tried uninstalling and reinstalling. Nothing.

IOptron Polar Scope

An excellent addition to the iOptron alignment sequence

The absolute best tool for astronomers and astrophotographers!

This is a must tool for anyone interested in astronomy.

Perfect apps, lots of information.

Highly accuracy, include many necessary sky observation information.
If world tide time table could be included, it would be the best❣️
Highly recommend!
