Sky Watcher 2.5mm Planetary UWA 58 deg Eyepiece

High-power lunar and planetary observing calls for an eyepiece that stays comfortable to use, and this Sky-Watcher Planetary UWA telescope eyepiece combines a 2. 5mm focal length with a wide 58 apparent field of view. Built around a modified Plossl design with five lens elements, it brings together fully multi-coated optics, low distortion and strong contrast in a compact format.

The 16mm eye relief and screw-off rubber eyecup make it a practical choice for extended sessions, including for spectacle wearers. A rubber grip adds secure handling, while the 1. 25-inch barrel is threaded for standard 1. 25-inch filters. This eyepiece sits within Sky-Watcher’s Planetary UWA range and is well suited to observers looking for a short focal length option for detailed views of the Moon and planets.
