Because adding Dioptrx to Nagler Type 6 eyepieces makes the eye relief quite tight, we recommend this only for Deep-Sky use, where your eye pupil enlarges. Some users might need to back off and lose some field to avoid eyelashes contacting the Dioptrx lens. We do not recommend using Dioptrx with Nagler Type 6 eyepieces in the daytime or bino-viewer applications.
[NOTE: All eyepieces with large eyeguards standard, such as Radians, 32mm Plossl and 8-24mm Zoom, can be comfortably used with bino-viewers when Dioptrx is attached].
For normal operation of any of these eyepieces without Dioptrx, the adapter can be left permanently attached since operation with the provided larger eyeguard is quite comfortable.
