Indeed, another consideration is that ASIAIR calculates the meridian position using the model-adjusted clock, whereas Gemini-2 gauges the limit's midpoint via the spirit level's state. Maintaining minor model time adjustments in Right Ascension (RA) helps keep the Limit points precise. As the Go-To Slew must occur reliably within the WGL.? Narrowly setting limit points requires an accurate level state. And the mechanics of long OTAs don’t allow wide settings.?
I appreciate your help.?

So by spirit level, I would guess you mean the "CWD" position the mount knows after a cold start. I've gotten to doing things this way: set up the mount and ota, balance then level the mount base spirit levels, then the two in the RA and dec, then cold start the mount. I think of this as "home" for this mount.

I am happy this mount worked out. It was frustrating at first. I wanted something made in this way (here, small company) that I could use with the air sometimes and finally after a bit of fuss (maybe a bad motor) I get very good guiding and reliable results.

I like the tripod attachment design enough to make it my standard for all of my mounts and have scared up adapters where needed and adapted a Berlebach tripod to this as well. I still use the heavy Losamandy tripod, but it's a beast. You can see a large black steel knob under the tripod top plate. The one flaw I see in the Losmandy tripod design is you cannot roughly rotate the mount. I am used to having this with other mounts. So the Losmandy base plate is attached to the Berlebach with a big 1/2" bolt so that I can rotate the mount a bit if find I am off by say 5 degrees when I go to polar align. Mechanically I am fairly certain it will be reliable.
