These 1.25" Ultra Flat Field Eyepiece are made to a high standard and feature a compact form factor. Integral to the design brief was the emphasis on removing field curvature, resulting in a flat, distortion-free image up to the edge of the visible field of view even in very fast (low focal ratio) telesocpes and binoculars. The eyepiece has oversized eyepiece lenses for the largest possible field of view and 27mm eye relief. This also makes them also suitable for spectacle wearers. A foldable eyecup is also provided for comfort. All lenses feature broadband multicoating (FMC) and blackened lens edges for maximum contrast. The nose of the eyepiece is threaded for 1.25" filters. This eyepiece also features an M43 thread for digiscoping use. We recommend this M43 to T2 adapter.

The APM UFF range of eyepieces offer quality comparable to reference products like the TeleVue Panaoptic but at a much lower price.
