Celestron 8-inch Aluminum Dew Shield

Key Features

• Minimises radiative cooling of the Schmidt corrector lens
• Prevents dew accumulation on the lens
• Enhances image contrast by preventing stray light infiltration
• Compatible with 8" EdgeHD, RASA, or Schmidt Cassegrain telescopes
• Integrated cable management slot
• Minimises radiative cooling of the Schmidt corrector lens: This feature ensures that your lens stays below the dew point for a longer duration, preventing dew accumulation and maintaining the quality of your viewing and astroimaging experience.
• Enhances image contrast by preventing stray light infiltration: By preventing stray light from entering your telescope, the Aluminium Dew Shield enhances the contrast of your images, resulting in clearer and more detailed astroimaging.
• Integrated cable management slot: This feature allows you to keep your setup neat and organised, preventing potential light pollution from leaking in and ensuring a smooth and efficient astroimaging process.

The Celestron Aluminium Dew Shield with Cover Cap is a crucial addition to your telescope setup, designed to safeguard your telescope tube whilst in use. Its primary function is to minimise the radiative cooling of the Schmidt corrector lens to the night sky, thereby maintaining the lens below the dew point for a longer duration and averting dew accumulation on the lens.

Furthermore, the Aluminium Dew Shield enhances image contrast by preventing stray light from infiltrating the telescope, resulting in improved viewing and astroimaging. The Aluminium Dew Shield is ideal for use with your 8" EdgeHD, RASA, or Schmidt Cassegrain (manufactured post-2006) telescope tube, having been meticulously crafted for your specific instrument.

Construction

The Aluminium Dew Shield provides a perfect, custom fit for 20.32 cm Celestron telescope tubes. The exterior of the dew shield is a rigid, aluminium cylinder that will not fold, flex, or deform.

Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit. We've also constructed the cover cap from durable yet lightweight aluminium.

When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging.

If you're an astroimager who enjoys using your Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar configuration or the RASA, you're probably used to running cables out the front of the dew shield. Simplify and streamline your setup with the Aluminium Dew Shield's integrated cable management slot at the base.

This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.

Enhance your setup

When purchasing this item, you will receive 2x adhesive Celestron logo labels. Use them on your dew shield or anywhere else you like! Check out the 20.32 cm Dew Heater ring and the Smart DewHeater and Power Controllers to optimise your setup for the ideal dew-free night of observing and imaging.
