Re: Tele Vue 'Blem' Eyepieces

I've puchased several NEAF "blems" over the years,
and was not able to detect any flaw except the
punch mark.

I've also seen a number of TV non-blems with obvious
optical flaws -- circular zones, bubbles in glass,
too much scattering in the cement, field stop in
wrong place, etc.

Go figure.
