Pentax XF 12mm

This is a beautiful Pentax spotting scope eyepiece. It works extremely well in scopes with long focal ratios. It's not a good eyepiece for sub-F/5 scopes (some edge distortion).

While edge performance isn't great in fast scopes the on-axis performance is excellent. I used mine a lot in an 8" f/5 scope.
