Omegon Flexible dew cap 4 inch (115-135mm)

Nothing is more frustrating than a perfectly aligned telescope whose optics fog up as soon as the air cools. The Omegon flexible dew cap 4 inch offers a simple, effective solution: it prevents water vapor from condensing on the lens or corrector plate of your telescope. This keeps your image clear and sharp, even on humid nights.

This dew cap is made of flexible plastic and features a dark velvet inner layer which minimizes reflections and blocks condensation. Thanks to the adjustable velcro closure attach it securely around the telescope tube. After use, simply roll it up - ideal for compact storage next to your eyepiece case or tripod.

With a compatibility range of 115 to 135 mm pipe diameter this hood is suitable for a wide range of telescopic systems in the 4- to 5-inch class.
