Ultra-Flat Magnetic Dust Cover — ZWO Seestar S50 Pro

Permanent optical protection with zero clearance obstruction during auto-parking and calibration

On the ZWO Seestar S50 Pro, forgetting to take off a bulky third-party lens cap before turning on the device or during an automated battery-save shutdown can strip internal gearboxes. Precision crafted in our workshop in Cannes, France, this ultra-flat magnetic dust cover eliminates this issue: it shields your front triplet lens from environmental hazards while letting the telescope arm fold fully into park position without removal.

🔬 Precision Mechanical Clearance for Grab-and-Go Stargazing

🔄 Zero Park Collision

Designed with sub-millimeter clearance tolerances, this cap stays flush against the optical housing. You can let the Seestar automatically park, pack it straight into its foam case, and travel with total peace of mind—your optics remain protected 24/7.

🧲 Fully Sealed Neodymium Magnets

High-strength neodymium magnets are inserted into internal cavities during active printing via a slicer pause routine. There are zero visible glue joints, zero risk of magnet pull-out, and total isolation from corrosive nocturnal dew.

Reliable Dust and Environmental Barrier

Engineered for real-world field conditions:

  • Dust, Pollen & Dew Shield: Keeps airborne particles and accidental finger smudges away from the front 50 mm objective when parked on a tripod.
  • Instant Magnetic Snap: Centers smoothly over the optic housing without forcing, scraping, or marring the factory chassis finish.
  • Technical Matte Black PETG: Printed using industrial-grade polymer that withstands intense daytime solar heat and freezing night temperatures.
  • Full Range Compatibility: Fits perfectly only Seestar S50 Pro.

"The real hazard with smart telescopes is an unexpected shutdown when battery runs out at 3 AM: the arm folds shut automatically. If a thick cap is on, the internal motor strains against the body. With this ultra-flat cover, you leave it on permanently during daytime or travel without risking internal gear stripping."
