Well... your mount is trying to move where we tell it to, but it seems to be dancing around it. For instance, at the point you noted, we asked your mount to go to RA 1.56055555555556 and it ended up at 1.56614486728729. At your scale, that is about 212 pixels from where you want it.
Well... I don't really know (or understand how to use EQMOD... a lot of our support issues come from EQMOD users though). Maybe @mads0100 is correct in his assessment.
