| This is a very good quality medium high power eyepiece with a surprisingly wide field of view. It is a good choice for resolving globular clusters to the core, picking out detail in smaller galaxies, locating smaller planetary nebulas against a busy stellar background, etc. It provides nearly the ideal 1mm exit pupil recommended for the sharpest images with an 8” f/10 Schmidt-Cassegrain telescope. A 1mm exit pupil typically matches the resolving power of the telescope to the resolving power of your eye, for exceptional lunar and planetary detail. The eyepiece has short usable eye relief that will severely limit the field for eyeglass wearers. Those who must wear eyeglasses while observing due to severe astigmatism would probably be better off using a Barlow and a longer focal length eyepiece with longer eye relief to reach this focal length, rather than buying this eyepiece for use on its own. |
