I have this eyepiece which is in mint condition
in every way except for what appears to be a small
scratch on the lens. I am not the original owner
and I believe that it was there when I bought it "LNIB"
However, it is difficult to see and I didn't notice it
for a couple of months. It doesn't seem to have any
adverse effect on the view, but you've been warned.
If anyone is interested please make me an offer.
