Sky Watcher 9mm Planetary UWA 58 deg Eyepiece

High-magnification lunar and planetary observing calls for an eyepiece that remains comfortable to use, and this Sky-Watcher 9mm Planetary UWA 58 eyepiece balances both. Built around a modified Plossl design with five lens elements, it pairs a 9mm focal length with a 58 apparent field of view for a broad, immersive view.

Fully multi-coated optics support strong contrast and low distortion, while the 16mm eye relief gives a more relaxed viewing position, including for spectacle wearers. A screw-off rubber eyecup folds down as needed, and the barrel is threaded to accept standard 1. 25-inch filters. Rubber grips around the body add secure handling when changing eyepieces at the telescope.
