Make the Moon Comfortable to Look At Through a Telescope
The Moon through a telescope can be blindingly bright — so bright that fine surface details like craters and ridges get washed out. This neutral-density (ND) lunar filter screws into any standard 1.25" eyepiece and reduces the Moon's brightness to about 25% of its original intensity, making observation comfortable and revealing surface details that are normally lost in the glare.
Key Features
- Reduces Moon brightness to ~25% — similar to an ND4 filter — for comfortable viewing
- Screws into any standard 1.25" eyepiece barrel
- Improves contrast, making craters and surface textures stand out
- Compact and lightweight at ~10g
