PrimaluceLab 120mm Dew Heater
The PrimaluceLab 120mm Dew Heater is placed on the optical tube to prevent optics dewing. A very common problem especially in winter and in sealed optical tubes, such as refractors or Schmidt-Cassegrain. These dew heaters, 12 V powered, heat the telescope preventing the formation of condensation on the optics.
This dew heater for 120mm diameter telescopes can be easily installed thanks to Velcro which ensures a strong and uniform fixing. Thanks to elastic fix, it can be installed on tubes from 120mm to 130mm diameter.
For their use, you need to have 12V power supply with power consumption from 360mA to 480mA. The power consumption varies depending on the heating mode that you choose. In fact the dew heater has a pressure switch that allows to vary the heating temperature from high to low. Also a led indicator is green color in the lowest temperature set and red color in the highest temperature set. The OFF LED indicates that the dew heater has no power. The power of the dew heater is through a female jack 2,5mm diameter.
