I am soon to be the proud owner of a new Sky Watcher EQ6-R Pro mount... I got my bi-annual bonus at work and decided this year instead of spending it on stupid stuff like bills and food, I am finally going to by this mount that I have been wanting for 5 years. However, it is unfortunately on back order so I am taking the time to really dig into the weeds on how to operate it and whatnot and a question I have for the seasoned astrophotographers pertains to periodic error correction.
From my understanding, PEC is the correction of the predictable errors found in worm drive gears but the mount needs a reference point and a calibration point for the PEC to be effective. However, I cannot find any information on how often that calibration needs to occur. Do I need to recalibrate it every time I set my telescope up or is the calibration stored permanently? Polar alignment is never perfect so I am wondering how one night's alignment that could be very good vs a following night's alignment that is ok but not great impacts that calibration. Also, I read that in order to get an accurate calibration, the worm drive needs to make one complete rotation... does that mean one complete rotation of the mount which is way more than one rotation of the gear, or is one rotation of the gear which is way less than one rotation of the mount?
Or am I completely over thinking all of this?
