Telescopes & Astronomy

• 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 and improves contrast - built-in heater strap gives additional protection

NOTE: Sirius Optics recommends that any dew heater strap or heated dew shield be connected to a dual channel dew controller and not directly to 12V.

This allows the user to regulate the current and temperature of the dew heater strap or dew shield. 

The recommended control unit is the Astrozap Duel Channel Dew Controller (Product No. 124474)

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.  

Made for the very popular Telrad finder scopes.

NOTE: Sirius Optics recommends that any dew heater strap or heated dew shield be connected to a dual channel dew controller and not directly to 12V.

This allows the user to regulate the current and temperature of the dew heater strap or dew shield. 

The recommended control unit is the Astrozap Dual Channel Dew Controller (Product No. 124474)

Flexible plastic dew shield, no notch

Dew shield to prevent dew appearance and improve contrast. Easy to fit. Suitable for 6”  telescopes.

Farpoint Dew Shield – Celestron 6SE SCT is a tough cover that protects optical equipment and allows for moisture-free observing sessions.

• This Aluminum Dew Shield with Cover Cap fits all 6” Celestron Schmidt-Cassegrain telescope tubes. It’s an essential accessory that protects the tube in the field. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, keeping the lens below the dew point longer and preventing dew from forming on the lens. The Aluminum Dew Shield also increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. Use the Aluminum Dew Shield on your 6” Schmidt Cassegrain telescope tube confidently, knowing it was created for your exact instrument.

• Fits 11” Schmidt-Cassegrain, EdgeHD, and RASA telescope tubes

• 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
