Sky Watcher 4mm Planetary UWA 58 deg Eyepiece

High-power lunar and planetary observing calls for an eyepiece that stays comfortable to use, and this Sky-Watcher 4mm Planetary UWA 58 eyepiece is built with that in mind. Its 4mm focal length and 58 apparent field of view suit detailed, high-magnification work, while a modified Plossl design with five lens elements combines with fully multi-coated optics for low distortion and strong contrast.

Comfort has been given equal attention. The 16mm eye relief provides a more relaxed viewing position, including for spectacle wearers, and the screw-off rubber eyecup folds down as needed. A rubber grip adds secure handling, and the 1. 25-inch barrel is threaded for standard 1. 25-inch filters, making it a practical addition to a telescope setup built around interchangeable eyepieces.
