Omegon Dew Shield 80 cm for 8-inch Telescopes

Omegon Dew Cap 80 cm for 8-inch Telescopes: dew-free for 8-inch optics

A dew strap works differently than a dew shield. Instead of shielding the optics, it holds the glass edge a few degrees above the dew point. This prevents water vapor from condensing on it, even at high humidity.

This is the size for the widely used 200 mm Schmidt-Cassegrain, a telescope whose corrector plate is notorious for fogging up quickly. With this strip, it stays clear all night.

Apply

Wrap the band around the tube, directly behind the lens or corrector plate. The flexible design follows the curvature, and the hook-and-loop closure keeps it securely in place, even when you move the telescope.

Regulate power

With a controller, you can continuously adjust the heating power. This saves electricity and prevents unnecessary warming of the optics, which can cause air turbulence in the tube at high magnifications.

Featured accessories

All LED strips in this series operate at 12V and have an RCA connector. For stepless dimming, use a controller; without a controller, the strip always runs at full power.
