These 14mm 70° AFOV (Apparent Field of View) 8-element 1.25″ eyepieces are included with every BT Series binocular telescope, so we don’t normally offer them for sale on this website. But we’re putting them here in the Replacement Parts section for those that want to use them in other binocular telescopes, such as the discontinued Oberwerk BT-100-45. Twist-up eyecup helps hold your eyes at the optimum distance. Can be used while wearing glasses with eyecups fully retracted. Sold in pairs.
