Damon,
It appears to be all 3 tubes partially why I am leaning towards HV. It
seems like if I could turn the the focus just a little more it would be
perfect. If I go the opposite way they get really blurry. I didnt really
notice it as blurry when it was here before customer just complained of it
at the beginning of the week.
Thanks,
