This 40mm Pentax is a bit of overkill for my
500mm FL APO, so it doesn't get used much.
Purchased new in April, this is in terrific
shape, and comes with caps and the original
Pentax protective plastic case.
For those who don't know, this is a wide-field
(65* AFOV) eyepiece that offers excellent
performance in a lightweight (14oz -- 1/2 the
weight of a 35mm Panoptic), low-cost
($234 new at ATWB) package.
I'm asking $210 plus actual shipping.
