Yes. In one instance I can remember you were backing up my star-to-star
observations with the Sno-T and scope A. With your new IC you would have
been spot one, and I would have been nominally 0.3' to 0.4' over on average.
Not impossible for me ;-) On the other hand I failed to do my own IE check
with the Sno-T and scope A, and I am convinced that changing focus can
affect index error with most scopes.
