In 2019 I upgraded the Three-legged Newt to a Celestron AVX mount. While the alignment process ultimately proved easy enough to learn, I never seemed to achieve especially impressive accuracy when using that alignment to locate objects. Selected objects (including calibration stars) were consistently at the very edge of the field of view (using a finder eyepiece with a 1.4 degree TFOV) I've done enough polar alignments for visual observing to discount polar alignment as the source of the this displacement. A minor annoyance, but an annoyance all the same.
Because I use the Newt in more than one location, I decided to purchase a Celestron SkySync GPS device and let technology handle a couple of set-up and alignment chores - time and place. (Yes, I'm that lazy. ) The persistent displacement during alignment and calibration was immediately reduced to an amount I now consider trivial. Selected objects for observation land well within that 1.4 degree TFOV, requiring a modest tweak at most to center the object. I've done nothing else different, so feel safe assuming cause-and-effect here.
So, I'm assuming the use of the SkySync brought this about. Am I off base thinking that my distance from the standard meridian for Mountain Standard Time (105 degrees west for MST, 110.98 W. for my location in Tucson) is sufficient to create the displacement I first saw? And that a GPS fix for where (and when) I am when I observe did, in fact, provide a measure of correction?
The kind of stuff you don't absolutely need to know to use the gear, but can't help wondering about.
