Dew Shields & Heated Dew Shields

The Celestron Aluminum Dew Shield with Cover Cap is an essential accessory that protects your telescope tube in the field. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, thus keeping the lens below the dew point longer preventing dew formation on the lens.

Use the Aluminum Dew Shield on your 9.25” Schmidt Cassegrain and EdgeHD telescope tube confidently, knowing it was created for your exact instrument.  

• Fits 8” Schmidt-Cassegrain, EdgeHD, and RASA telescope tubes
• Helps prevent dew formation on the Schmidt corrector lens
• Prevents off-axis glare from entering the optical system
• Rigid body with a velvet-lined interior surface to reduce stray light
• Two adjustable clips for easy installation and disassembly
• Cable management at the base of the shield—perfect for using the Fastar/Hyperstar configuration or using in conjunction with the Celestron Dew Heater Rings
• An included cover cap keeps your telescope free from dust when not in use

• Prevents dew from forming on your Schmidt-Cassegrain or EdgeHD corrector lens
• Fits 6” and 8” optical tubes
• Cutout accommodates telescope dovetail rails
• Felt-lined interior surface captures moisture and reduces stray light
• Rolls up for easy transport
