The series of photos below show the process of installing our dew heater. The process is fairly straight forward.

You will need the following:

  • Silicone adhesive (optional)
  • Q-tips (cut off the cotton tip)
  • Razor blade

Begin by clearing some space. Lay a clean towel on the table to protect the mirror and prevent screws from rolling away.

Place heater on the glass and insert heater and mirror into holder sleeve. Place the white polyester batting on top of the heater. The batting will keep the heater in contact with the back of the mirror. Run the wires out through the notch in the holder base and re-attach the sleeve to the base. Be sure all the wires pass cleanly out through the small hole on the side of the base. Insert mirror assembly into spider hub and secure with wing nut on end of stem.

Place a small piece of self adhesive velcro on a spider vane adjacent to the spider hub. Attach heater battery pack to the velco. Leave the LED indicator light and temperature sensor visible and behind the holder. Tuck them in between the collimation screws out of the light path.
