Thanks, Brian, but no, that is not it.? I even did a factory reset just to be sure nothing was stored that was interfering in some way.? I have checked and re-checked location data -online, with my wife's smartphone GPS app, and also with a Losmandy-supplied GPS unit, and it was all the same, and I set up at the exact same spot every time I'm out.? I've entered and re-entered that data just to be sure.? I use UTC, not local time, and have checked and re-checked that too.? At some point, you have to be 100% confident!? And from the number of "pointing" issue threads I've seen about Losmandy mounts here and elsewhere, well, I realize a good bit of it could be user error, but certainly not all of it.? But thanks for the suggestion in any event.? I just want to assure you that those things are NOT factors.
