The Robtics USB Dew Heather has an USB connection and is powered through by 5 volt USB power. The dew heather can be fixed to the telescope tube with velcro and will radiate heath to the optics. This will prevent the optics from dropping below the dew-point and therefore prevent fogging up of the optics. A supplied controller can vary the amount of heath generated.
