Product Details

Original APM description below:

The APM 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.
