produce high contrast, high resolution, and superior flat field
characteristics. The visual effect of these eyepieces with their long
eye-relief and their 82° apparent field is truly a full-immersion
experience. These eyepieces come with a twist-up rubber eye-guard that
raises to the desired height, for the comfort of the observer, and as
