Omegon W&W 4-channel dew heater controller
Humidity can cause dew to form on objectives, finder scopes and eyepieces. The Omegon W&W 4-channel controller powers several heater bands and lets you set each output to suit the optic being protected. This makes it possible to tailor heating instead of running every band at full power.
PWM output is adjustable in 25% steps per channel. The unit runs on 12 V and includes a 2 m cable with a cigarette-lighter plug and integrated 4 A fuse. LEDs show the selected power level. A clip allows mounting on a telescope, mount or tripod. RCA outputs connect to compatible heater bands. Heater bands and power source should be ordered separately.
