The Artesky FlatField eyepiece series is characterized by sharp images and a flat view up to the outer edges of the field of view; the excellent quality of the optics, combined with a high-end anti-reflection treatment, make these eyepieces a must-have for the amateur astronomer. Observation remains pleasant and relaxed even for a long period, in fact the FlatField eyepieces have a removable Twist-UP rubber light shield to comfortably rest the eye; the 10mm eye relief is also useful for those who use glasses. High correction of field curvature, one of the most common optical aberrations in eyepieces, is guaranteed in the FlatField series allowing you to take full advantage of the provided framing, having sharp images not only in the center but also at the edges of the eyepiece! You will observe celestial objects as they really are, without any distortion of the visual field. The eyepieces are completely blackened inside to avoid annoying reflections and are also coated in rubber to ensure a firm grip even with gloves in winter. The size of the lens will impress you at first sight, however when you look into it the clarity of the image is nothing short of incredible! Extra-flat field of view up to the edges ED elements for sharp, contrast-rich images Wide-angle eyepiece with apparent field variable depending on the focal length from 53° to 65° Comfortable observation with TWIST UP system and 16mm pupil extraction, excellent for those who wear glasses Very stable removable shells Multilayer coating on all lenses 31.8mm (1.25") fitting with 1.25" filter thread Parfocal eyepieces between them - Changing eyepiece and focal length does not require refocusing The FlatField series eyepieces have different focal lengths and the apparent field varies according to the focal length; we report an explanatory table below | FlatField 8mm Eyepiece | 60° | Eye relief 19mm | 5 optical elements | | FlatField 12mm Eyepiece | 60° | Eye relief 19mm | 5 optical elements | | FlatField 16mm Eyepiece | 65° | Eye relief 19mm | 6 optical elements | | FlatField 19mm Eyepiece | 65° | Eye relief 19mm | 6 optical elements | | FlatField 27mm Eyepiece | 55° | Eye relief 19mm | 6 optical elements |
