ASToptics Dew heater 120cm (12"/14" Telescopes)
Unheated dew caps can only delay the condensation of moisture on the telescope optics, but cannot prevent it in the long term. In most cases, the precipitation comes in a flash and the observation night is over. So why not use a dew cap heater?
The heating tape directs the heat directly to the dew shield, optics or other accessories and thus prevents any dew precipitation.
