When I set my mount up, I first do six to twelve points manually (with some stars on each side of the meridian), then do a few short 25-30 point automated runs, tweaking polar alignment between each short run, then do my long automated run of 180 or more points once I have polar alignment good enough. Then I turn ProTrack on. Five minutes unguided at f/11 and 3911mm focal length (EdgeHD 14) with perfectly round stars is routine. Ten minutes unguided at the same focal length is achievable, but takes more time tweaking polar alignment. Certainly worth doing for a long term set up (in the backyard), but not usually worth the time at a remote site.
Can you detail the T-Point polar align method?

I ran a couple of 20 point automated runs the other night, but the azimuth kept oscillating between 4 click East and 4 click West. I'm OK with doing the automated run, I just synced on one known star and let it go. What I'm unsure of is what do I have to do after adjusting the mount? I cleared the model, is this right?
