Use our eyepiece calculator to figure out what the 31mm will deliver on your scope.

    "Despite the presence of no less than seven optical elements, these [Nagler] eyepieces provide images which are noticeably brighter than those obtained with many quality orthoscopics, with superb image sharpness and contrast. Even though these oculars are quite expensive, the serious planetary observer would do well to consider employing this type." - Don Parker et al., Introduction to Observing and Photographing the Solar SystemTeleVue Product Number: EN5-31.0
