Become an astrophotography enthusiast with the Celestron 9.25"" Aluminum Dew Shield with Cover Cap, a vital accessory designed to safeguard your telescope tube during field use. This high-quality dew shield significantly reduces radiative cooling of the Schmidt corrector lens, keeping it below the dew point for extended periods and effectively preventing dew formation on the lens. The Aluminum Dew Shield enhances image contrast by blocking stray light from entering the telescope, optimizing your viewing and astroimaging experiences. Specifically designed for 9.25"" Schmidt Cassegrain and EdgeHD telescope tubes, this dew shield provides a perfect, custom fit, ensuring your equipment's protection.Constructed with a rigid, durable aluminum exterior, the dew shield maintains its shape without folding, flexing, or deforming. The interior is lined with velvet, absorbing any additional stray light and excess moisture, creating optimal contrast for viewing and imaging.
