CAM10 – Dew Not Heater for Camera Lenses and Small APOs.
The CAM10 – Dew Not Heater is designed for 10 inch (254mm) circumference lenses and smaller APOs i.e. those with a tube diameter of around 80mm, such as most 60mm – 72mm APOs. For larger and smaller optics there’s a wide range of other sizes available in the Dew-Not range.
A small overlap or shortfall in size does not affect performance.
By adding a portable 12 volt battery and supply cable you can keep your optics dew free, home or away.
Dew forms when your optics cool below the Dew Point, by raising the temperature of the lens or corrector by only a small amount, you can stop dew forming in most cases. A lens dew shield or shade is also useful in conditions of high humidity and rapidly falling temperatures.
