Mint condition 40 mm Konig 2" eyepiece with caps and box.
This eyepiece is fully multi-coated with a large 60 degree field of view. It's blackened lens edges along with other design characteristics, provide the highest contrast available in an eyepiece of this focal length. It has excellent eye relief and razor sharp images to the edge of the field! (Note: this is *not* their older model, the 40mm MK-70.)
