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.
