About this product

Model:  lynxastro_heated_shield_5
Part Number:  lynxastro_heated_shield_5

Lynx Astro premium quality flexible heated dew shields, made in the UK. 

Robust design using modern materials for high performance and long life!

Simply wrap the dew shield around the end of your telescope tube near the optics and secure it with the integrated Velcro. A gentle heat is then transferred to the optics until the temperature is slightly warmer than the dew point. 

Dimensions are 53cm long and 19cm wide. Please check the circumference of your telescope to ensure it will provide a good fit (a few cm are necessary for the velcro areas to overlap). 

An inner black felt liner prevents stray light entering the telescope so enhances contrast.

Will I need a Dew Controller? 

A simple 12V Dew Heater Supply Cable can be used to connect to a suitable 12V power-supply. When connected this way the heating element is essentially running on full-power. This won't harm the heater but with smaller telescope apertures it might result in the optic being warmer than necessary which can effect the view and waste energy. The solution then is to use a Dew Controller that regulates the heat (also enables you to use more than one heater tape). Lynx Astro heated dew shields and heater tapes are compatible with most good dew controllers, including those manufactured by Lynx Astro & HitecAstro. 


  • Suitable for use with most 5" / 127mm diameter telescopes.
  • Modern heating element provides even heat distribution and low power consumption.
  • Produces 8W of heating power.
  • Requires approximately 0.68Ah at 12v / full power.
  • Outer thermal insulating layer prevents heat loss.
  • 2m silicone cable remains flexible even at low temperatures.
  • RCA / Phono Plug with moulded strain-relief - works with most dew controllers.
  • Velcro  ensures a snug, secure fit.
  • Internally flocked with black felt to prevent reflections.
  • Smooth inner fabric protects the telescope's finish (doesn't scratch or mar the surface).
  • 12v power supply required.
  • Two year no fault replacement warranty.

Lynx Astro dew shield
Friday, 6 May 2022  | 

Good quality dew shield/heater, the outer casing is quite stiff but has a felt lining so is a snug fit on my 127mm scope, the velcro catch is really strong so when it is attached it is not going to move, also it gives off enough heat to stop my scope misting up, as it seamed you only had to breathe in it's direction and you could not see anything, it is well worth the money, the silicone cable is very flexible so is easy to tuck out of the way when attaching to your rig, a good buy, very pleased.
