Its 8mm eye relief is quite reasonable for this focal length, although it will somewhat limit the field for eyeglass wearers. Since the Astro-Tech field is wider to begin with than most other eyepieces in this price range, most eyeglass wearers won’t find the minor vignetting to be a drawback. All in all, this Astro-Tech Series 6 is a sharp, high contrast 1.25" eyepiece that most observers would be happy to own.
