Product Info

Manufacturer Description

The 1.25" UltraFlat Field Eyepiece features a high quality standard and a very compact design, which is designed to remove the field curvature at the edge, resulting in a flat, distortion-free image up to the edge of the visible field of view. The eyepiece has over - sized eyepiece lenses for the largest possible field of view and a 20mm eye relief - also suitable for spectacle wearers, the adjustable eyecups allow a comfortable view

All lenses (8 lenses in 5 groups) have a broad-band-multicoating (FMC) and blackened lens edges. The plug-in sleeve is equipped with a thread for 1.25" filters.

The largest diameter of the eyepiece body is 49.5 mm. Weight: 208 grams

      5.0 APM 18mm UFL 1.25" Eyepiece




      A very solid well built eyepiece. Quality lens/excellent supple rubber eye guard . Its an expensive looking eyepiece, giving a very sharp/clear 15x power in my small 390FL refractor.
