Description
Sky-Watcher 6mm Planetary 58° UWA 1.25" Eyepiece
The Sky-Watcher 6mm Planetary 58° UWA Eyepiece is a high-magnification telescope eyepiece designed for detailed observation of the Moon, planets, and double stars. With its 6mm focal length and 58° apparent field of view, it provides high magnification while maintaining a comfortable and practical viewing experience.
The eyepiece uses a modified Plössl optical design with five lens elements. Its optical surfaces are fully multi-coated (FMC) to improve light transmission and help produce bright, sharp, and high-contrast views. The 16mm eye relief is particularly useful for comfortable observation and can accommodate many eyeglass wearers.
Designed for High-Magnification Observation
The 6mm focal length is well suited to high-power observing. When combined with a suitable telescope and good atmospheric conditions, it can reveal fine details on the lunar surface and planetary disks, while also being useful for observing close double stars.
Its 58° apparent field of view provides a comfortable viewing window at high magnification. The adjustable rubber eyecup helps position the eye comfortably and can help reduce distracting stray light during observation.
The standard 1.25" (31.7mm) barrel fits most telescope focusers and star diagonals designed for 1.25" accessories. The barrel also includes a standard 1.25" filter thread, allowing compatible lunar, planetary, or other telescope filters to be attached.
