Dew Heater Bands – (Various Sizes)

If the optics fog up, this normally means an early end to what could have been a successful astronomy session and there’s nothing more frustrating for an Astronomer or Astrophotographer when this happens on rare crystal clear nights. Heater bands reduce the risk of dew on the lens or on the corrector plate by slightly heating the front lens of your telescope just slightly above the surrounding air temperature which prevents the dew settling on the lens.

A heater controller is also required for these heater bands which allows you to regulate the temperature and therefore achieve an optimal result with a minimum amount of power. You can also combine the heating sleeves with dew shields to further protect your lens or corrector plate from dew formation.

Features:

• Optimal heat utilization. On the outside, the cuffs are insulated to prevent the wasteful radiation of heat outwards.
• Particularly flexible due to the elasticated velcro fastener, making it possible to use it on different tubes.

Specs:

• Power consumption: 12V DC, 4.2W – 350mA

Note: Heat Controller Power Supply required – (Sold Seperately).
