Rally, I got the figure from the Tpoint model which says 12.2 arc seconds after 74 points.
With the TSA I get very accurate pointing. Typically only a few seconds ( what looks like a mill or two on the screen) at most from the cross hairs to the target.
Time I did a sync around 5 pm with my usual server. I doubt that would make much of a difference.
Yes sub 10 second pointing at 10 points, I get around 4" from 10-20, then as it gets further into the model is blows out a little to around 40" prior to adding terms. Once terms are added it get more accurate and I follow the significant differences ideas we have discussed in the past (ie watching the sigma etc in the model).
PA looked fine after 20 points and the mount has not moved since my Tpoint run on the TSA.
Since Greg gets a similar result I suspect that focal length does influence the pointing accuracy, so I will hunt down what is flexing if anything.
