I don't bother much?with building a model.? I get pretty good polar alignment with the polar scope.? Then I pick an alignment star that's close to the eventual target and sync on it. Then I go to a bright star as close as possible to the target and sync? on it. Then I go to the target.? And that's it.?
I have actually? never built a model.? I'm 100% imaging in the 3 month's I've had my G11G.? I have a permanent pier now, and got polar aligned to 30 arc seconds.? I start with CWD set by eye with the levels on the RA and DEC.? My go-to my first target in the Eastern sky is usually only a few arc-min off.? I can tell this by the display on the ASI Air.? It shows the coordiantes of the target, and the plate solved coordinates.? So that seems pretty good to me.? I will then do a sync and center to get spot on.
When it flips to the West, it can be WAY off - like 10+ degrees.? I don't really know if this is an ASI AIr thing, or a gemini thing, as perhaps the gemini having only one sync point on the East and no points on the West doesn't know what to do with itself.? But a plate solve and recent works just fine.??
I add this commentary because I believe the mechanical accuracy is there in these mounts - as evidenced by a very close go-to of the first target from a very accurate polar alignment.? ? I need to explore the software? more.
