Pentax XF12 - 12mm 60 degree 1.25 inch Eyepiece

All of Pentax's eyepieces are constructed with a high-refraction, low-dispersion lanthanum glass that consistently delivers bright, high-resolution images with minimal distortion. Designed for use with Pentax brand spotting scopes and with astronomical telescopes with appropriate 1 1/4" focusers.

Featuring a wide 60° field of view and generous 18mm eye relief for comfortable glassing, the Pentax XF smc 8.5mm Eyepiece is designed for use with their 100, 80, and 65mm spotting scopes or any astronomical telescope or spotting scope that accepts standard 1.25" eyepieces. Extra-low dispersion lanthanum glass in the 6-element/4-group lens design provide a balanced image with minimal aberrations, while the proprietary smc anti-reflection multi-layer lens coatings prevent reflection for optimal light transmission. The eyepiece is constructed to be water resistant, easily withstanding light rain or dew. For digiscoping, there is a 30.5mm mounting thread under the removable twist-up click-stop eyecup for attaching your rings and adapters.
