AST Optics Premium USB heating sleeve from Europe
On a clear night, the optics cool down. The humidity condenses as dew on the optics and thus prematurely ends observation or photography.

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

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