Omegon W&W 2-channel dew heater controller
Humid air can cause dew on objectives, finder scopes and eyepieces, interrupting an observing session. The Omegon W&W controller lets you match heater output to each optic. Its two channels are adjusted independently and can power up to four heater bands with RCA connectors, allowing, for example, the objective and eyepiece to be controlled separately.
PWM output is adjustable in 25% steps. Power is supplied at 12 V through a 2 m cable with a cigarette-lighter plug and an integrated 4 A fuse. LEDs indicate the selected setting. A clip allows the unit to be attached to a telescope, mount or tripod. Heater bands and power source are sold separately.
