Product Features in Detail

Extreme High-Power Resolution

The 2.5mm focal length is designed to push your telescope to its theoretical magnification limit. It is the perfect tool for "splitting" difficult binary stars or viewing the smallest details within lunar rilles and craters.

Glasses-Friendly Viewing

In many high-power eyepieces, the eye relief is so short that users must press their eye against the glass. The 20mm Long Eye Relief of this model allows you to see the entire 58° field while keeping your glasses on, a significant ergonomic advantage.

High-Contrast Internal Baffling

To maintain clarity at such high magnification, the internal barrel is baffled and blackened. This prevents internal reflections from bright objects (like the Moon) from washing out the image, ensuring you see the darkest blacks and brightest details.

Enhanced Field Correction

Sky-Watcher has optimized the lens geometry to ensure that stars don't "smear" near the edges. This edge-to-edge precision is vital for high-power viewing, as it allows you to utilize the entire field of view for observation.

Secure All-Weather Handling

The inclusion of thick, knurled rubber grips means you won't struggle to swap eyepieces when the dew falls or your hands are cold. This tactile design ensures you have total control over the accessory, preventing accidental drops.

Threaded for Technical Filters

At 2.5mm, targets like the Moon can be incredibly bright. The integrated filter threads allow you to easily screw in a Neutral Density or Moon filter to reduce glare, or a color filter to enhance specific planetary features without needing extra adapters.
