Sounds like a very solid routine. Do you clear your sync history or simply do a fresh sync on top of the older ones?

I haven't been doing a fresh sync when I start a new T-point model. Just using the last one done. Not sure what the manual says on this point.

Scrubbing the sync history clean though is what caused my mount to act as if it were set to Northern Hemisphere even though in the BCS it said it was set to the Southern Hemisphere.

The accurate polar alignment feature is a nice new feature and it seems to give superior results.

This latest bug is just an indication of insufficient functional testing being performed on code that they push out. Simple test cases should have identified it.

The process I follow:

1 = Home mount
2 = Expose image after homing and synch directly to the image.
3 = Automated tpoint collection using 6 points near synch position
4 = remove the user added 6points from the list and then extend it out to say 50-80, whole sky.
5 = finish tpoint, generate super model and apply it.
6 = Perform polar alignment wizard adjustment against a star with ~98+% reliability.

start process again, but with 200+ points and finish at super model.

If the above is wrong, I am happy to do try something else but synching to an actual plate solved image seems far more reliable than rough eyeball, especially when you switch off your mount and re-home it.
