Kring Are you saying that for greatest accuracy, I should be using LST which more accurately represents my personal time based on longitude location of my scope?
There are two spherical coordinate systems involved with an Equatorial mount.
One is the coordinate in the sky, which we know as Right Ascension and Declination.
Your mount keeps another (mechanical) coordinate system that refers to the Polar Axis in terms of Hour Angle. An Hour Angle of zero is the position of the mount where the OTA is pointed right at the Prime Meridian that runs above the horizon (there is another meridian that is 12 hours away that runs directly below your feet). This is called the Hour Angle of your mount.
That is how the mount's polar axis is pointed.
The relationship between the mount's motors and the sky is related by
RA = LST - HA, or conversely
HA = LST - RA.
So, you you know the RA of an object (which, except for nutation, precession and proper motion, is mostly fixed) you can point to it if you also know the LST.
LST is all that matters in astronomy. An object transits the Prime Meridian when the LST reaches the RA. This is also the time that you need to flip the pier side of a German mount.
Everything else (UTC, local time, longitude) are only necessary to derive LST.
There are iOS/iPadOS apps out there that displays LST. Even SkySafari has a LST clock, just look at the Advanced tab in the Time window.
The only program that does not display LST is ASIAIR. I have no idea if it is because ASIAIR is UTC based or because it simple refuses to display proper astronomical time for the sake of the simple minded 1,2,3 people.
Back in the good old days, our mounts (including my EM11) come with a polar "circle." At the start of each night, you use LST to set the angle of this "circle." And from that point on, the "circle" reads out the approximate RA directly. This "circle" only lives in the firmware of a mount with some modern mounts, although you can still find them in premium mounts.
