Very comfortable eye position:The big eye lens with 21 mm diameter allows relaxed observing. Even beginners will be convinced by an image that´s contrasty and free of straylight. If you wear eyeglasses, just leave the eyecup in the lower position and you can observe the full field.
High image definition, good contrast and flat field:Up to six lens elements, each fully multicoated results in a high contrast much over the normal level. Its brilliance and transmission level make this eyepiece a top choice for Lunar and Planetary observations and for deep sky also.
