Dew-Not Dew Heater Strips
Dew Heater system with top value for money
for 12V power supply. Compatible with TS and Kendrick controllers

High quality dew heater strips that can be attached to variable tube diameters with a Velcro strip. The optics are heated up by a small amount. This effectively prevents the formation of dew without causing disturbing local seeing (air currents rising from the heated optics).

The strips can either be connected directly to a 12V power source using the optional cigarette lighter plug, or can be used with a controller that allows you to adjust the heat according to your needs. Please see below for the different options:

Direct 12V power supply

Regulated power supply using a dew controller
