Eyepiece Adapters for Dioptrx
These adapters convert eyepieces with small eyeguards to larger eyeguards, so Dioptrx can be installed. Note that these eyepieces have shorter eye relief than others recommended for Dioptrx, so to minimize any vignetting, it's best to use these for deep-sky applications where your eye pupil is large.
When used for bino-viewers, you may encounter "nose relief" limitations because Dioptrix reduces the normal eyepiece eye relief.
