The Dragonfly is an essential piece of equipment for your observatory. It provides a simple means to centralise all power switching and sensing. In addition it can respond to various 'conditions' using user defined scripts and control almost any aspect of your observatory. It is particularly suited to remote installations or where you wish to control your observatory from in your home. The Dragonfly allows you to turn all power on/off and can react to inputs from other devices such as the Lunatico Cloudwatcher or other sensors and react however you demand.

A typical scenario might be that the input from a Cloudwatcher warns it is Unsafe due to bad weather. The Dragonfly sees this and could tell a roof control system like the Talon to close. At the same time it can notify you on your phone and start to instruct your camera to warm up, put the mount in park, close all applications and finally shut down the PC. With some simple additional wiring and using the Dragonfly App, you can also turn on your PC from you phone before logging on to start an imaging session.

The Dragonfly is configured for control of 2 wire mains but also features a separate earth connection for use with 3 wire main. We recommend that if switching mains the Dragonfly be housed in a suitable enclosure for safety reasons. Alternatively an optional safety cover (blue terminal cover shown above) is available to prevent accidental contact with terminals carrying mains voltage.
