Celestron Dew Heater Ring 5 Inch for SC Telescopes

Celestron Dew Heater Ring – Protect Your Optics from Condensation

The Celestron Dew Heater Ring is an accessory designed for Schmidt-Cassegrain telescopes (SC) with 5-inch aperture. It wraps around the corrector lens and effectively prevents the formation of dew and condensation during night observations or astrophotography.

• Fits 5-inch SC telescopes – easy tool-free mounting
• Aluminum construction ensures even heat distribution and durability
• Gentle heating protects optics without overheating
• Ideal for astrophotographers who need clear images even in humid nights

What sets the Celestron Dew Heater Ring apart

Unlike simple heater bands, the aluminum ring distributes heat evenly around the entire front lens. This prevents dew without creating thermal turbulence. The material is corrosion-resistant and weighs only 500 g, so it doesn't affect telescope balance.

Ideal for...

Amateur astronomers with a 5-inch SC telescope in humid regions – near coasts or in alpine valleys. Also for astrophotographers who take long exposures and must avoid any disturbance from condensation.

How to use the Celestron Dew Heater Ring

Simply place the ring around the corrector lens of your SC telescope. Power is supplied via a USB port or optional power adapter. Temperature can be adjusted manually or with an optional controller. After observing, remove the ring and store it dry.
