The Celestron Aluminum Dew Shield with Cover Cap represents an indispensable accessory essential for safeguarding your telescope tube during outdoor field observations. This dew shield plays a vital role in mitigating the effects of radiative cooling on the Schmidt corrector lens, ensuring that the lens remains below the dew point for an extended period, thereby effectively preventing dew formation on the lens. In addition, the Aluminum Dew Shield significantly enhances image contrast by acting as a barrier to block stray light from entering the telescope, thereby improving the quality of your viewing and astroimaging experiences. You can confidently utilize the Aluminum Dew Shield with your 9.25” Schmidt Cassegrain and EdgeHD telescope tube, knowing that it has been meticulously designed to perfectly complement your specific instrument.

Construction:

The Aluminum Dew Shield is precisely tailored to provide an impeccable, custom fit for 9.25” Celestron telescope tubes. Its exterior is composed of a rigid, aluminum cylinder that maintains its structural integrity without any risk of folding, flexing, or deformation. Within the dew shield, a plush velvet lining effectively absorbs any residual stray light and excess moisture, thereby creating an optimal environment for enhancing contrast during both viewing and imaging sessions. To secure the dew shield onto your telescope tube, simply utilize the two adjustable clips to ensure a snug and secure fit.

Furthermore, the accompanying cover cap is crafted from durable yet lightweight aluminum. When your telescope is not in use, placing the cover cap onto the dew shield protects your Schmidt corrector from stray dust particles. Additionally, the cover cap facilitates the swift and effortless acquisition of dark frames for imaging purposes.

For astroimagers who typically employ their Schmidt-Cassegrain or EdgeHD telescopes in the Fastar/Hyperstar configuration, the Aluminum Dew Shield simplifies and streamlines the setup process. Featuring an integrated cable management slot at the base, this dew shield provides a convenient solution for organizing essential cables (such as those for our Dew Heater rings) without the potential for light pollution to intrude. Moreover, the dew shield includes cutouts designed to accommodate dovetail rails on both the top and bottom of the telescope tube, ensuring compatibility with various configurations.

Enhance Your Setup:

Upon purchasing this item, you will receive two adhesive Celestron logo labels that can be affixed to the dew shield or any other location of your choosing.

To optimize your setup for an ideal dew-free night of observing and imaging, consider exploring the 9.25” Dew Heater ring and the Smart Dew Heater and Power Controllers as valuable additions to your equipment.
