Kendrick Firefly Heaters - Dew Prevention For Optics
Kendrick's FireFly heaters are designed for the astronomer who requires a dew prevention system that is both economical in price and power. Although unable to perform up to the high standards as our original Premier brand of heaters, astronomers and anyone else requiring heated optics for dew prevention can depend on Kendrick FireFly heaters to perform under all but the most demanding observing conditions. Note that if your observing site gets temperatures that approach freezing on the nights you like to observe, you should consider the Premier line of heaters.
Having lower power requirements than the Premier heater line, these heaters will extend the life of your battery between charges. Using a different heater technology but operating under the same principle as Kendrick Premier line of heaters, these heaters will mildly disperse heat into your optics without compromising the figure of your telescope or camera optics.
As well, because of our unique manufacturing process, the FireFly heaters will direct their heat into your optics instead of losing it into the atmosphere. We have had these heaters independently tested for heat transmission and the resulting images below clearly show the effectiveness of our build technology. These heaters are very effective in directing most of the heat into the optics which is important if dew is to be prevented.
The image to the left shows the outward facing surface of a Firefly heater, while the image to the right shows the inside, or optic heating side of a FireFly heater. This surface shows a +20º C difference from the outward facing surface proving the effectiveness of our manufacturing process in directing the heat into your optics.
Kendrick's employs high quality Velcro, elastic and connectors with these heaters. All the FireFly heaters come branded with our permanent, white identification label for easy identification in the field.
AN IMPORTANT NOTE: Some competing manufacturers of low wattage heaters make claims that their heaters, with half the wattage of Kendrick Premier line of heaters, will perform just as well as the Premier heaters, and at a much lower price! Well, this is true to a point but once you get down to temperatures approaching freezing, forget it, it just ain't gonna happen! You cannot escape the laws of Physics. Half the wattage means half the power, end of story. We make no such claims about the FireFly heaters. They do have their limitations.
