Did I get this wrong, is this not meant for manual pointing? In which case corrected does not seem the right description, it will observe the sky rotation and add 15" to the pointing error every second, I have to manually correct that when things move out of the field of view.
Yes, the pointing shown in the app will always be correct, just the object will move out of the field of view. You need to manually track the object using an equatorial mount, or use a clock drive or similar.
