The system automatically measures and compares temperature of the air and mirror. If both temperatures start to equalise, the system will react promptly in advance and slightly rise mirror’s temperature. As a result dew do not condense on the mirror. The system is very efficient depending on capacity of powerbank and atmospheric conditions it allows for couple of days of observation. System operates with a 5V source, USB port .
Options available for all Taurus telescopes. Power supply is not included
