Altair DewZapper Dew Heater for RC Secondary Mirror or CCD Camera Filter wheel
A flexible, split ring design, makes the heater very easy to install. It fits onto the back of the secondary mirror housing and is held in place by a thin layer of silicone glue or any glue (user provided) which resists moisture. Made with genuine nichrome wire embedded in a flexible silicon layers.
Dimensions are 65mm inner diameter, 90mm outer diameter, however the silicon is flexible and can be used on a smaller diameter mirror by overlapping the ends.
To install the heater without removing the secondary spider vanes, two convenient plugs are provided for you to disconnect the wire making installation easier. PLEASE NOTE: You must wrap the plugs with insulation tape BEFORE connecting your dew heater else they can short out.
2 year warranty in normal use with a professional dew controller such as Pegasus or Kendrick. Do not use with direct 12v DC current, always use a dew controller to regulate the power to the heater.
Tip: Only use the minimum power to heat your camera and clear dew from the front optical window, else you will end up warming the sensor.
