It strikes me what we are measuring is the distance between the center of the scope and the reflected image on the first pass. Then we are moving away to see that the distance remains the same (beams are parallel). In that post he states, "Poor telescope optics might present a problem." I remain convinced, at least with my scope and any I have tested, as well as the observations of others on the list, that changing the focus can affect side error and IE. So if we focus the scope for the smallest dot, we can only check IE at that focus point. Yes? So it might not remain the same once we refocus for our eyes?
