APM Ultra Flat Field 18mm Eyepiece 65° FOV
The 18mm 1.25" UltraFlat Field Eyepiece features high quality in a very compact unit designed to remove field curvature; resulting in a flat, distortion-free image to the edge of the visible field of view, even in very fast telesocpes. The eyepiece has oversized eyepiece lenses for the largest possible field of view and 20mm eye relief - suitable for eyeglass wearers and the rubber eye cup allows for a comfortable view. All lenses (8 lenses in 5 groups) have broad-band-multicoating (FMC) and blackened lens edges. The plug-in sleeve is equipped with a thread for 1.25 "filters.
