Provided your location (LAT , LONG and time) are correct then you can rely on T-Point to tell you how to Polar Align.

Homing the mount first syncs the mount to where it should be. Delete all syns in bisque TCS then just point to a star using SkyX somewhere between east and due south above 45 degrees but below 90.

The scope will get close to this without a full model. Use the mounts ALT and AZ settings to center the star you just pointed to. This will get you within a few arc mins.

Once done then send mount home again. Now start your t-point polar alignment run. Move to a star again center it in cross hair or CCD and sync (better still take and image, inage link and plate solve it) then sync on the photo. You then go into t-point add on and add about 9 - 12 more targets all on same side of meridean. then click supermodel button. It will calc your offsets and tell you which way to move the PMX knobs. This will get you to sub arc min.

Once you have don this once you then need to delete the t-point model and the sync and start again. ie send mount home, slew to a star, sync, then start another 12 points t-point run. Follow instructions again on knobs.

If you start to oscilate. ie one run says move 2 tics then next says - 2. Then half what it tells you. So if it says 2 ticks west. Do 1 tick west. Eventually it will report no more adjutsment needed and you are done.

its fast and accurate. No need to drift align anymore.
