I have a pulsar 2.7 m dome and the azimuth controler, this has a relay which trips when a 12 volt supply is sent closing the shutter. The current is switched using an Hydron rain detector sensing rain. I also have a HitecWeatherDeluxe cloud/rain sensor. Will ACP respond to HitecWeatherDeluxe weather alerts to close the shutter and open again when the sky clears.
