[PhilW]

I bought a pair of these for use in my binoscope, but the magnification is slightly too high for comfortable two-eyed use; image merging gets rather finicky. So I am keeping one for cyclopean use (since it is a lovely eyepiece) & selling the spare.

These eyepieces are light, compact & have many optical virtues; let me just mention the comfortable 18mm eye relief.

$150 shipped. Includes original Pentax box & caps.
