About this product

Model:  lunatico_acnsel05
Part Number:  ACNSELDR

The Lunatico Dragonfly is a roll off observatory controller for remotely control of your observatory. 

6 Reasons to buy the Dragonfly

  1. Smart: can perform operations by itself (for example, send you an email or push message, reboot the router if no internet, WOL, etc…)
  2. Smartphones support: custom control app
  3. Universal: with ZeroConf, access it from anywhere – no configuration required
  4. Versatile: roof open and close operations can be customized. Actions can be launched when a sensor or relay changes.
  5. Secure: password protection available (3 levels)
  6. Supported: complete ASCOM and INDIGO and INDIlib roof and switch drivers

With the Dragonfly you can:

  • Switch on and off lights and equipment
  • Open and close the observatory roof
  • Control 8 relays (4 of them double NO/NC, and 4 NO)
  • Monitor the AAG Cloudwatcher and check for safe or unsafe weather conditions
  • Monitor, using magnet or mechanical sensors the mount’s position, the status of the roof…
  • ZeroConfiguration network system
  • ASCOM switch & dome interfaces
  • Improved internal web server:
    • Simple page to manage the relays and sensors,
    • Javascript for web page integration

ASCOM support is available, and also INDIGO and INDIlib. And with a free application for mobiles and tablets.

This Version 2.0 Dragonfly includes the following new/enhanced features when used with the new software version:

  • Relay restrictions (do not close relay if…)
  • Roof control from the main panel
  • Improved log window
  • New DragonflyConfigurator software to manage the internal settings
  • New macros, actions the Dragonfly can perform autonomously, very powerful (internet connectivity testing, email / push message sending, wake on lan, relay open / close, sensor checks, etc.)
  • Internal clock, with timezone support (useful for macros)
  • 3 level password protection
  • improved ZeroConf connections
  • Log automatically recorded to disk, including any relay activity

… and of course some internal improvements and fixes.

The new hardware also addresses some network problems, found mostly at shared observatories with a lot of network activity, and improved relay protection in case of power supply noise.
