Dew controller's

[Mick.G.]

Recieved a Hitecastro 4 chanel controller + an Astrozap dew shield from FLO on friday, so I set the scope up to see where the best place for the controller to be placesd.

The dials on the controller got me thinking, should I start at the min' setting, half way, or on full for the night?

I'd be glad to know how you guy's set out at the start of the night, to save me faffing abuot on what few nights we do get.

Regards Mick.G.

The settings are going to depend on what you're trying to keep dew off... and how wet it is outside.

Hello see if this helps

Adjusting the Output

Turn the control knob corresponding to the heater tape you wish to adjust. The

output of the red LED will change to indicate the level of power being output.

Turning clockwise increases the output while turning anticlockwise decreases the

power output to that channel.

General Dew Removal Advice.

Dew removal tapes do not generally apply enough heat to cause degradation of

seeing under normal conditions. However we do recommend that you should not

leave your heater tapes on full power all of the time. On good nights you may

leave the heaters on at about 20% to keep your optics dew free. Experimentation

will determine the minimum power required to keep your telescopes free of dew

given your location. The developers have found that a setting of around 50% is

enough to keep optics dew free on even a relatively damp and still night.
