I have two RPi4 systems with KStars installed used with two Sky-Watcher mounts - the AZ-EQ5 (connected as a Sky-Watcher EQMOD mount), and the AZGTi via WiFi connected as itself. In each case, I notice that the DEC axis indication for one mount in Park position is 90° as I would expect, but the other indicates 89°46' 51". I also note that the RA values indicated are 12 hours out of step with each other. Can anyone suggest why this is?
My intention is to pre-rotate a mount by precisely 60° to the East prior to carrying out Polar Alignment using two 30° steps to the West, hence making the mechanical alignment adjustments with the mount back in the Park position (although admittedly Unparked!). I can still do this with a bit of simple maths, but just wonder why there are these differences. See screen grabs.....
