Nothing is more frustrating than a perfectly aligned telescope with optics that fog up as soon as the air cools down. The Omegon flexible dew shield 4 inch offers a simple, effective solution: it prevents water vapor from condensing on your telescope’s lens or corrector plate. This keeps your image clear and sharp, even on humid nights.
This dew shield is made of flexible plastic and features a dark velvet inner layer that minimizes reflections and prevents condensation. Thanks to the adjustable velcro closure, you can securely attach it around the telescope tube. After use, it rolls up easily – perfect for compact storage alongside your eyepiece case or tripod.
With a compatibility range of 115 to 135 mm tube diameter, this shield is suitable for a wide range of telescope systems in the 4- to 5-inch class.
