T-Point and ProTrack in The Sky X Pro slews your mount/scope to many points in the celestial sphere (number of points is user defined, from say 20 to 200+), takes a say, 10 sec exposure, plate solves that image and then compares the results to where the mount “thinks” it is pointing versus actual pointing.
When you apply those corrections to the mount, pointing accuracy and tracking accuracy are much improved over the uncalibrated mount.
Wit my C11 at 2800mm, I have been able to image at 60 secs unguided with no evidence of star training and a couple of experimental 180 sec exposures looked just as good.
This is for the SB MX+ Mount.
