interesting thread,
I just recived my cats eye infinity xlk (dual pupil) and black cat and hotspot .
when i do the carefully de collimation by vic maynard, i get the P + P3 to stack using the center pupil, then inserting the black cat, align the hotspot, then re inserting the xlk, and stacking the hotspots again, there is residual error where there shouldn't be.
but as soon as i adjust and restack its perfect and the black cat confirms the same.
I guess the question is, how sensitive is the auto collimator to the centerspotting? as the 10" ring wasn't the right fit to my mirror, it was smaller by about 2mm diameter.
and also making sure that im doing it right :S
