The Kendrick FireFly heater is designed for the astronomer who requires a dew prevention system. Astronomers and anyone else requiring heated optics for dew prevention can depend on FireFly heaters to perform under all but the most demanding observing conditions. Having lower power requirements than other heater lines, this heater will extend the life of your battery between charges. It will mildly disperse heat into your optics without compromising the figure of your telescope or camera optics.
As well, because of Kendrick's unique manufacturing process, the FireFly heater will direct their heat into your optics instead of losing it into the atmosphere. Each heater independently tested for heat transmission and the resulting images below clearly show the effective build technology. It is very effective in directing most of the heat into the optics which is important if dew is to be prevented.
