The Aluminum Dew Shield with Cover Cap is designed to perfectly fit all 6” Celestron Schmidt-Cassegrain telescope tubes, serving as a crucial accessory for safeguarding your telescope in the field. This dew shield plays a pivotal role by mitigating radiative cooling effects on the Schmidt corrector lens, ensuring that the lens remains below the dew point for an extended duration, effectively preventing the formation of dew on the lens. Furthermore, the Aluminum Dew Shield significantly enhances image contrast by effectively blocking stray light from entering the telescope, resulting in an improved viewing and astroimaging experience. You can confidently utilize the Aluminum Dew Shield on your 6” Schmidt Cassegrain telescope tube, knowing it has been meticulously crafted to perfectly suit your specific instrument.

Construction:

The Aluminum Dew Shield offers a precise and custom fit for 6” Celestron telescope tubes. Its exterior is composed of a rigid aluminum cylinder, maintaining its structural integrity without any folding, flexing, or deformation. Internally, the dew shield features a velvety lining, effectively absorbing any additional stray light and excess moisture, which in turn creates optimal contrast during your viewing and imaging sessions. To secure the dew shield onto your telescope tube, use the two adjustable clips to ensure a snug and secure fit.

Additionally, the accompanying cover cap is constructed from durable yet lightweight aluminum. When your telescope is not in use, simply place the cover cap onto the dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also facilitates the quick and hassle-free acquisition of dark frames for imaging purposes.

For astroimagers who prefer using their Schmidt-Cassegrain telescopes in the Fastar/Hyperstar configuration, you'll appreciate the Aluminum Dew Shield's integrated cable management slot at the base, which simplifies and streamlines your setup. This slot provides a convenient means to organize essential cables, such as those for our Dew Heater rings, without the risk of light pollution intrusion. Furthermore, the dew shield incorporates cutouts to accommodate dovetail rails on both the top and bottom of the telescope tube, ensuring compatibility regardless of your specific configuration.

Enhance Your Setup:

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

To optimize your setup for an ideal dew-free night of observing and imaging, consider exploring the 6” Dew Heater ring and the Smart Dew Heater and Power Controllers as valuable additions to your equipment.
