Lynx Astro 20cm Dew Heater Strap for Large 2'' Eyepieces or Finders
Built to last with a rugged construction and modern materials, these heater straps are designed for efficient dew prevention and long-term durability.
To use, simply wrap the strap around the telescope tube close to the optics and secure it using the integrated Velcro and elastic fastening system. Once powered, the heater gently raises the temperature of the optics just above the dew point—effectively preventing moisture from forming.
Strap Length: 20 cm – Please check the circumference of your eyepiece or finderscope to confirm proper fit.
Do You Need a Dew Controller?
You can connect this heater strap directly to a 12V power supply using a basic 12V Dew Heater Supply Cable. In this setup, the strap will operate at full power continuously, which will not damage the strap itself. However, for smaller aperture telescopes, this might lead to excessive heat, potentially degrading your viewing experience and consuming unnecessary power.
The recommended solution is to use a Dew Controller which:
Regulates power output to match actual dew conditions
Allows simultaneous use of multiple dew heater straps
