The Celestron Aluminum Dew Shield with Cover Cap is a vital accessory designed to safeguard your telescope tube during field observations. This dew shield plays a crucial role by mitigating radiative cooling effects on the Schmidt corrector lens, effectively ensuring the lens remains below the dew point for an extended period, thus preventing the formation of dew on the lens. Additionally, the Aluminum Dew Shield significantly enhances image contrast by effectively blocking stray light from entering the telescope, resulting in improved viewing and astroimaging experiences. You can confidently use the Aluminum Dew Shield on your 14” EdgeHD, 36cm RASA, or Schmidt Cassegrain telescope tube (manufactured after 2006), knowing it has been meticulously crafted to suit your specific instrument. For further details, please refer to our FAQ section.

Construction:

The Aluminum Dew Shield boasts a precision design, providing a flawless, custom fit for 14” Celestron telescope tubes. Its exterior features a robust, rigid aluminum cylinder that maintains its shape and structure without folding, flexing, or deforming. Internally, the dew shield is lined with velvet, effectively absorbing any residual stray light and excess moisture. This design choice ensures optimal contrast during your viewing and imaging sessions. To secure the dew shield onto your telescope tube, utilize 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 or EdgeHD telescopes in the Fastar/Hyperstar configuration or the 36cm RASA, the Aluminum Dew Shield simplifies and streamlines your setup with its integrated cable management slot at the base. This feature 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 night of observing and imaging, consider exploring the 14” Dew Heater ring and the Smart Dew Heater and Power Controllers as valuable additions to your equipment.
