P. Bombas Wouldn't it be possible for ZWO to include an option where the user manually performs an alignment to Polaris, after which the Seestar can calculate the deviations based on three other stars in different locations, without taking the level and compass sensors into account? In this way you avoid interference from external factors (materials) or am I seeing this wrong?"
All PA routines need a feedback system for the user to know what and how much to adjust the mounts mechanical alignment in Alt and Az. The Seestar uses the compass and accelerometer to provide that feedback. In the case of Non SMART telescopes, i.e. a standard telescope, the feedback comes in the form of viewing the star selected for PA through an EP or on a screen feed from a camera. The user then centers the star by adjusting the Alt and Az controls to achieve PA. ZWO could used the traditional method by showing us a PA star on the phone or tablet with a cross-hair for adjustment, but decided their way is easier for most users. It is very simple but, as we all have experienced, if there is anything out of calibration with one or the other sensor we get non-sense feedback.
