Dew-Not was founded by John Marstiller, the author of six United States patents and multiple international patents related to resistance heaters and innovations in flexible electrical circuitry. John has been designing and manufacturing thin film heating elements for over 30 years, and has used these products in home heating and military thermal imaging applications as well as in his highly regarded telescope heaters.
High Point recommends Dew-Not heaters. Why? Because they draw a lot less power and cost significantly less than other telescope heaters on the market. Drawing less power means your battery will last longer and Dew-Not heaters are very well made right here in the USA. Each strip has a standard plug that will fit most dew controllers, including the one manufactured by Dew-Not!
With heater strips to fit a range of apertures, from 76mm (3 inches) to 406mm (16 inches) there’s no need to worry about condensation forming on your optics again. For example, the Dew Not 3" Dew Heater Strip has an adjustable velcro strap, making it the ideal choice for smaller scopes.
Dew-Not also produces strips that have been specially designed to fit eyepieces and finders. The Dew Not 1.25" Eyepiece Dew Heater Strip emits heat over two thirds of its surface, providing even heat distribution and ensuring no localized hot spots or burnouts.
