Product Features in Detail

Superior Planetary Resolution

The 5mm focal length is a high-power specialty lens. It is engineered to provide the magnification needed to capture the subtle color variations in Jupiter’s belts, the gap in Saturn’s rings, and the intricate shadows within lunar craters.

Glasses-Friendly Ergonomics

High-power eyepieces often suffer from very short eye relief, forcing the user to "squint" or remove their glasses. With 20mm of eye relief, this eyepiece allows you to maintain a comfortable distance from the lens, making it one of the most ergonomic high-power options available.

High-Contrast Internal Baffling

To ensure "jet-black" backgrounds and bright targets, the internal barrel features anti-reflective threads and blackened lens edges. This meticulous attention to detail prevents internal glare from bright objects like the Moon from washing out the image.

Edge-to-Edge Sharpness

Sky-Watcher has designed this UWA model to rival premium "boutique" eyepieces. The field edge correction is superb, meaning you won't experience the blurring or "stretching" of stars near the perimeter of your view.

Rugged Field Durability

The all-metal anodized body is not only aesthetically pleasing but also provides structural integrity. It can withstand the temperature fluctuations common in stargazing without the fogging or misalignment issues often found in plastic-bodied alternatives.

Tactile Non-Slip Handling

Swapping eyepieces in the dark can be risky. The inclusion of deep, knurled rubber grips provides a tactile surface that is easy to hold, even when wearing heavy winter gloves, reducing the risk of accidental drops.
