USAGE WITH CELESTRON SMART
DEWHEATER CONTROLLERS
For the most effi cient power usage while keeping your optics free from
dew all night, we highly recommend using the dew heater rings with
the Smart DewHeater Controllers. These controllers utilize the ring's
built-in thermistor to provide just the right amount of heat to prevent
dew based upon the ambient temperature, ambient humidity, and
temperature of the Schmidt corrector.
To use the dew heater rings with the Smart DewHeater Controllers:
1. Remove both the ring's power jack and thermistor jack from their
storage clips on the ring and insert them into the cable management
clip (Figure 11).
Fig 11
2. Attach the cable management clip onto the front cell of the
telescope near the jacks as indicated previously (Figure 12).
Be sure not to pull on the cables too hard when doing this.
Fig 12
3. Connect the heater ring's power jack to one of the Smart DewHeater
Controllers heater output ports using the included extension cable.
4. Use the thermistor extension cable that comes with the Smart
DewHeater Controllers to connect the heater ring's thermistor jack
to the corresponding thermistor port located on the controller box
under the heating port that the ring is now connected to.
The dew heater ring is now ready to be used with the Smart
DewHeater Controllers. For more information on powering and
operation of the Smart DewHeater Controllers, refer to the instruction
manual that comes with the controller.
The dew heater rings are also generally compatible with third party
dew heater controllers. Use the included extension cable to connect
the dew heater ring's power jack to the controller's heater output port.
NOTE:
The dew heater ring's integrated thermistor is generally NOT compatible with 3rd party
dew heater controllers. To utilize "smart" functionality for most effi cient power usage,
you will need a Celestron Smart DewHeater Controller.

USE WITH DEW SHIELDS
To achieve the highest level of dew prevention, use the heating rings
in conjunction with a dew shield. While not mandatory, a dew shield
will cut down on the amount of power the dew heater ring needs to
use to keep the optics clear of dew. This will result in even better
power effi ciency.
The Celestron Aluminum Dew Shields have a cable management clip
built-in so that they can work seamlessly as a system with the dew
heater rings (Figure 13). If you regularly observe in very heavy dew
conditions, we recommend using both a heater ring and dew shield,
especially with the larger aperture 11" and 14" models.
IMPORTANT NOTE:
Be sure to fi rst remove the dew heater ring's jacks from the integrated
clip in the Aluminum Dew Shield before attempting to remove the dew
shield from the telescope. Otherwise, you can damage the jacks and the
heater ring can become inoperable.
