The APM HI-FW 84° 12.5mm eyepiece provides an ultrawide 84 degree field of view. The complex optical design has been optimized for edge sharpness even when using fast telescopes. With 23mm of eye relief, the APM UWA 30mm eyepiece is comfortable to use with eyeglasses.
Each optical surface features broadband multi-layer coatings. In addition, the body is fully blackened for high contrast and stray light suppression. The solid 1.25" barrel includes an M28.5 filter thread, allowing you to connect any standard 1.25" mounted filter.
