Dew heater for secondary mirror


Sizes available to fit all apertures.
Secondary mirror heating system automatically senses the air temperature and the mirror temperature, then maintains the secondary at a preset (adjustable) temperature above the ambient air temperature. Gently warms the secondary at 2-4 watts when on full. Six evenly spaced contact points for optimal thermal distribution. Uses a 9v battery (smoke alarm battery) mounted at the holder, eliminating the need for wires across the spider. No more heat ropes! On/off sensor and LED indicator included.

$75
