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.

Dragonfly now hosts its programming internally meaning it does not rely on an active PC program for control. It can use scripts for total automation but also offers powerful macro control using conditional logic such as If, Then, Or, And logic. In addition it can execute scripts direct to Ascom. This would allow a Dragonfly to control the motor of a roof, and also monitor the position of this and a mount. It can send a mount to park using a script, but using conditional logic, only allow the roof to close once parked.

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.

The Mk2 Dragonfly now features an internal PC to allow for more powerful programming options.

This version of the Dragonfly features two DIN Rail (35mm Rail) mounts on the back of it allowing it to be vertically mounted onto DIN Rail. This makes for a far easier installation in cabinets and racks.
