Rugged ABS
Providing the backbone of the Apertura 4″ Dew Shield for Celestron 4SE is premium ABS. Flexible, durable, and thermally insulating, ABS provides your Celestron NexStar 4SE Telescope with a rigid wall of protection against the elements when installed, and a flat, flexible sheet when your session is over. This rugged material is also resistant to the elements, ensuring your shield lasts for years to come!

Dew and Light Shield
Apertura has paired ABS backing with an excellent felt flocking lining for an effective barrier against the outside elements. This combination acts as a wall against the outside air, providing passive dew protection by helping trap a pocket of air in front of the Celestron NexStar 4SE’s front element. This extends the time it takes for dew to form on your optics, allowing you to enjoy an entire session free from moisture or helping an active anti-dew solution work more efficiently. The additional cone in front of the optics also makes light’s barrier to entry higher, helping stop sources of off-axis light from hitting your optics and lowering contrast with the flocking halting any light that does pass from reflecting off the shield itself.

Telescope Compatibility
This dew shield has been designed specifically for the Celestron NexStar 4SE Telescope. Simply overlay the sections of hook and loop to lock the shield in a cone, and slip the shield over the front of the telescope tube. A strip of foam provides the gentle pressure needed to keep the shield in place, and protects your telescope’s finish!
