This binoviewer heater consists of two 1” x 6.5” dew heater strips with 5.5” cables terminated by male RCA plugs. A two female to one male RCA Y-jack connects the two heater strips to a separate 3’6” power cord terminated by a male RCA plug for connection to the heater control unit. The heater strips fit 1.25” eyepieces with a maximum barrel diameter up to 1.5” (40mm).
One side of each heater strip is sponge-insulated. This directs the warmth of the heater element into the eyepieces, rather than being lost into the atmosphere, so that less energy is needed to keep your eyepieces moisture free. The entire back (label side) of each heater strip is Velcro. There is a Velcro tab on a 2.5” elastic strap on one end of each strip. The heater strips are wrapped around the eyepieces, label side out. When you pull the strap tight and press the Velcro tab onto the Velcro back of the heater, the elasticity of the strap holds the heater in place on the eyepiece.
Each heater strip draws 0.19 amps at full power (0.38 amps total, although power consumption at normal operating levels will generally be 40% to 60% less, as the normal standard controller setting is medium to low).
