This time-saving cooling system features three fans which have been custom designed to fit the Orion XX14i, XX14g and XX16g GoTo Dobsonian primary mirror cells. All three small fans work in tandem to help reduce the amount of time needed for the telescope to reach thermal equilibrium with the ambient air temperature of your observing location. You'll enjoy peak performance from your XX14i IntelliScope, XX14g GoTo or XX16g GoTo Dobsonian without having to wait as long for the air inside the telescope to cool down to the same temperature as your stargazing site. Each fan boasts 33.4 CFM (cubic foot per minute) air flow to help significantly accelerate cooling of your Dobsonian telescope's optics. The fans operate quietly without vibrating, and they mount easily in threaded holes on the the XX14i, XX14g or XX16g's primary mirror cell with included hardware. For best results, run the Orion Three-Fan Cooling System prior to using the reflector telescope. You can also use the cooling fans intermittently between observations to compensate for any ambient temperature changes that may occur. Power is supplied using the included battery holder which accepts 8 D-cell batteries (batteries not included). Since the Three-Fan Cooling System current draw is a low 0.36 amps, a full battery holder with 8 D-cells will provide over 24 hours of use.
