Overview
Plastic Dust Cap 48 mm Inner Diameter Push-On Cap for Telescope Eyepiece and Objective Depth 7 mm Black Optical Protection

The plastic cap with a 48 mm inner diameter protects eyepieces and objectives with an outer diameter of 48 mm during storage and transport. It is pulled over the edge of the optics to cover the front lens, preventing dust and small debris from settling on it. It is made of lightweight black plastic, so it does not add any burden to your equipment. The cap has no springs or catches; it is applied by pressure and removed by pulling. It is suitable as a replacement for a lost original cap or as an addition to optics that never had a cap.

The cap has the shape of a low cylinder with a flat top and a ribbed surface. The depth of 7 mm ensures that the cap hugs the edge of the eyepiece or objective, covering the entire front surface. The ribs around the edge facilitate gripping, even in the dark while observing the night sky. The value of 48 mm indicates the inner diameter of the cap, so please measure the outer diameter of your optics before selecting. For a set of eyepieces with different diameters, you can freely supplement caps in various sizes.

The cap is suitable for telescope eyepieces, smaller objectives, and other optical parts with a cylindrical end with an outer diameter of 48 mm. It replaces a lost original cap or complements an eyepiece that was never supplied with a cap. If you store multiple eyepieces in one case, each can have its own cap, keeping the lenses clean even after prolonged storage. The thin wall of the cap adds almost no volume to the eyepiece, allowing it to fit into precisely cut foam inserts. Before purchasing, we recommend measuring the outer diameter of the optics with a caliper.

Occasionally wipe the cap with a dry or slightly damp cloth to prevent dust from entering. Only place it on the optics when the lens is clean and dry. During observations, keep it in your pocket or in a compartment of your bag to avoid losing it among other accessories. Do not expose the plastic body to high temperatures for extended periods.

The 48 mm dust cap helps keep the front lens of the eyepiece or objective clean between observations. It is useful for astronomers and photographers who transport their equipment in a case or bag. It is made of plastic and the smooth flat top covers the entire front surface of the optics. Before ordering, measure the outer diameter of your device and select the appropriate size.
