Protect your eyepieces from dust, debris, and scratches. Available in both 1.25” and 2” sizes, eyepiece caps and plugs serve two purposes. The cap fits securely over the lens end of the eyepiece, and the plug is inserted into the open end of the eyepiece. Both are designed to keep debris and fingerprints away from your optics. Eyepiece cases come in a wide variety of sizes and are gauged on the size of the eyepiece. These “bolt style” plastic cases have a foam bottom, and the top threads over the bottom until the eyepiece is held securely in place so that they work for a variety of heights. Our cases are also specially chosen to avoid any offgassing that would be harmful to your optics.
