Details

Keep the lenses of your Seestar S30 Pro clean and dust-free during storage. This custom-designed cap fits snugly over the front aperture, protecting against dust, debris, and scratches — so your optics are always ready for a clear night sky.

3D printed from a special glow-in-the-dark thermoplastic polyurethane (TPU), the cap is flexible enough to form-fit the front molding of the lens cell, securing firmly with three retaining ridges. Unlike rigid plastic caps (PETG, ABS, etc) that can crack or warp over time, TPU is highly resilient — it handles bumps, drops, and temperature swings without losing its shape or grip. It's also resistant to oils and moisture, making it a durable long-term companion for your gear bag.

The glow-in-the-dark feature isn't just a novelty, it's useful in the field. In daylight, the cap appears translucent white, blending in cleanly with the scope. But charge it under any light source and it comes alive in the dark with a brilliant neon blue hue, making it easy to spot on a table, in a bag, or on the ground during a late-night session. It's the little detail that saves you from that frustrating moment of wondering where you set it down.

Designed specifically for the Seestar S30 Pro, the cap installs while the scope is in the open position and presses firmly into place. The three retaining ridges grip the lens cell securely without being difficult to remove. It's also low-profile enough to stay on when the arm folds closed, so you can pack up quickly without having to think twice.
