The Celestron Dew Heater Ring - 8-inch is a user-friendly dew control system for your 8" Celestron Schmidt-Cassegrain telescope. This custom-fit dew heater is the most efficient way to prevent dew from forming on your corrector plate during cool observing nights. Unlike generic strap-style dew heaters, this provides uniform heating directly to the optics.

 

Seamless Integration

To install this dew heater ring, you simply remove the plastic retaining ring on the front of your telescope's optical tube and replace it with the Celestron Dew Heater Ring. The celestron dew ring then provides a constant, gentle flow of heat directly to your corrector plate, offering superior telescope dew & moisture protection.

 

Key Features

• Integrated Design: This telescope dew heater becomes a permanent part of your telescope for a clean setup with no cumbersome straps.

• Efficient Heating: Provides the right amount of heat to keep your corrector plate just above the dew point without introducing tube currents.

• Power Options: The Celestron dew heater ring - 8-inch can be powered directly from a 12V DC source for constant heating.

• Controller Compatible: For optimal performance and precise temperature management, combine this dew heater with the Celestron Smart DewHeater Controller (sold separately). This provides the ultimate in automated dew control.

• Complete Solution: This is a comprehensive solution for telescope dew & moisture protection.
