Just noticed this article over a year after it was posted. The article prompted me to mic up the barrel on my own 21mm Hyperion which was purchased as part of Baader's introductory promotion.

My eyepiece's barrel measured 1.246" at the top and 1.249" at the end, a difference of only 0.003" (0.08mm). I wonder if anyone else has checked their Hyperion eyepieces and noticed any taper or irregularity in the barrels of any of them.
