AST Optics Premium USB heating sleeve from Europe

On a clear night, the optics cool down. The humidity condenses on the optics as dew, ending observation or photography prematurely.

Heating sleeves increase the temperature of the optics minimally, reducing the risk of dew without causing air turbulence. The new USB heating sleeves only have a slight heating effect, they are very economical in consumption and do not require any extra regulation.

Caution: Do not connect the heating sleeve to a computer, this can destroy the USB port!
