Hi Justin,
Looking at the eta images the first looks like it is pretty well centered and square, the second looks offset a little and slightly magnified but showing a lot of coma still, I would be checking if you have the right coma corrector like a baader or paracorr and not a field flattener for a refractor also check if the spacing is correct to the sensor plane and that the T-ring is all nice and square. I don`t think there is a problem with the scope it`s self.
cheers Gary
