Explore Scientific 82° Series 1.25" 6.5mm LER Waterproof Eyepiece

The 82° Series 6.5mm LER provides high-power, ultra-wide-field views with comfortable Long Eye Relief — ideal for detailed planetary observation without the cramped eye position that short focal length eyepieces often demand. At 82°, the field of view is dramatically wider than standard designs, and the lanthanum glass optics deliver the sharpness to fill it.
