The Celestron Aluminum Dew Shield with Cover Cap stands as an indispensable accessory essential for safeguarding your telescope tube during outdoor field observations. This dew shield plays a vital role in minimizing radiative cooling effects on the Schmidt corrector lens by preventing the lens from cooling to the night sky's temperature, thereby keeping it below the dew point for an extended period. This, in turn, effectively prevents the formation of dew on the lens. Additionally, the Aluminum Dew Shield significantly enhances image contrast by acting as a barrier to block stray light from entering the telescope, resulting in an improved viewing and astroimaging experience. You can confidently employ the Aluminum Dew Shield on your 8” EdgeHD, RASA, or Schmidt Cassegrain telescope tube (manufactured after 2006), knowing it has been meticulously designed to perfectly match your specific instrument. For further details, please consult our FAQ section.

Construction:

The Aluminum Dew Shield is tailored to provide an impeccable, custom fit for 8” Celestron telescope tubes. Its exterior comprises a sturdy, rigid aluminum cylinder that maintains its shape without any folding, flexing, or deformation. The dew shield's interior features a plush velvet lining, which effectively absorbs any residual stray light and excess moisture. This thoughtful design choice enhances contrast during your viewing and imaging sessions. To securely attach the dew shield to your telescope tube, utilize the two adjustable clips to ensure a snug and secure fit.

Additionally, the accompanying cover cap is crafted from durable yet lightweight aluminum. When your telescope is not in use, simply place the cover cap onto the dew shield to safeguard 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 accustomed to using their Schmidt-Cassegrain or EdgeHD telescopes in the Fastar/Hyperstar configuration or employing the RASA, the Aluminum Dew Shield simplifies and streamlines your setup. Its integrated cable management slot at the base offers a convenient solution to organize essential cables, such as those for our Dew Heater rings, without the risk of light pollution interference. Furthermore, the dew shield includes 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 8” Dew Heater ring and the Smart Dew Heater and Power Controllers as valuable additions to your equipment.
