Clayton,
As a previous owner of a G11T, I can tell you that Gemini 2 and the Losmandy mount is very accurate,? repeatable, and reliable.
Not sure what scope you use, I have used a 2600mm fl Maksutov to a 550mm fl refractor.?? I have done visual through the scope to line Polaris up and used Sharpcap.? Sharpcap was on the refractor.?
That being said, the first modeling star, I do modeling, is always off but generally in the FOV of a low power eyepiece, Maksutov scope being used here. After centering and aligning, that second star is closer, the third closer yet.? I typically do 5 - 6 stars per side, east and west.? When I use Sharpcap for polar aligning the first star is off,? but always in the FOV of my 533 chip camera. Again, after aligning 5 or 6 stars everything is pretty much in the center.
I use Sharpcap with the refractor, don't have a big chip camera to allow use for the Mak.?? I do have the luxury of using Sky X T Point for PA, using it the mount is always dead on with either scope.
It seems to me that Gemini builds two models, one east and one west.? Now my ground is marked, I have plates on the concrete to put the legs of my portable pier in, so I am in the same location every night.? If you can, I'd recommend marking the ground where you set up.
The mount is very accurate, model a bunch of stars east and west or plate solve.
My experiences,?? Joe
