Dew heaters are essential accessories to avoid the condensation of dew on lenses, mirrors and SC correcting plates. They incorporate an electric resistance that gently heats up the telescope to stop any condensation. The dew heater bands have to be placed on the optical tube in correspondence with the optical element.
They can be powered with a variable DC power source up to 12V or through one of the EAGLE control units. To optimize the power absorption, the dew heater can be controlled by ECCO (Environmental Computerized COntroller) that measures the dew point and communicates with EAGLE to regulate the voltage accordingly.
The Prima Luce Lab dew heater for 300mm tubes can be tightly locked around your optical tube by using the velcro patch. The closing strip is elastic and allows to connect it to telescopes with a diameter up to 300mm - 350mm.
The dew heater can be powered by a female 2.5mm RCA jack.
