The new Sky Watcher 4mm Planetary UWA 58 degree eyepieces are perfect when observing exquisite planetary and lunar detail at high magnification
These completely multi-coated eyepieces, which are built with five lens elements and are based on a modified Plossl design, are distinguished by their broad 58 degree field of vision, low distortion, excellent contrast performance, and comfortable operation.
With their screw-off rubber eyecups that fold down and their roomy 16mm eye relief, all models are comfortable for people who wear spectacles.
Rubber handles provide security to each model, and the eyepiece barrels are threaded to use standard 1.25" filters.
