APM Ultra Flat Field 18mm Eyepiece 65° FOV
The 1.25″ Ultra Flat Field 18mm Eyepiece features a high quality standard and a very compact design. Importantly, it is designed to remove the field curvature at the edge of your field of view. Hence, this results in a flat, distortion-free image up to the edge of the visible viewing area. Significantly, this is evident even in very fast telescopes. Notably, the eyepiece has over – sized eyepiece lenses for the largest possible field of view. In addition, a 20mm eyerelief (also suitable for spectacle wearers) and foldable eye-rubber allow for comfortable viewing. Significantly, all lenses (8 lenses in 5 groups) have a broad-band-multi-coating (FMC) and blackened lens edges. Finally, the plug-in sleeve is equipped with a thread for 1.25 “filters. All in all, the Flat Field 18mm Eyepiece will make a wonderful addition to your telescope accessories collection.
