SELETEK is Lunatico's original astronomical 
peripheral controller

ARMADILLO is the second version of Seletek and 

PLATYPUS is the new Seletek designed for remote control.

  • Automated focuser
  • Instrument rotator
  • Automated cooling fan control
  • Independent control of any controller pin, manual or automated (depending on temperature delta), useful not only for fan control but also for dew heater bands.
  • Filter wheel control (stepper based, not USB filter wheels!)
  • Any two (three in the case of the Platypus) functions at the same time

First version of the INDI focuser driver:

* covers focuser, for one port only
* for armadillo and platypus devices
* no need for external drivers in Linux
* for OSX users, a driver will be available to download soon from:

... more INDI drivers coming soon.


- A new, bombproof usb connection,
- Firmware update dedicated mini-usb port (since software version 3.0 / firmware 2.0 - released summer 2010 - this mini-USB is no longer needed; one you have these versions installed, you'll perform all future upgrades using the normal (big) USB cable)
- A more accurate temperature sensor, and
- Extra internal isolation for more security.

And already available:
-... and we are always willing to develop other utilities from your suggestions, please contact us.  

The focuser and the rotator software are ASCOM compliant

And, now, also INDI driver!

Platypus, the Seletek designed for remote control.

With all the features of the Seletek Armadillo plus network connection (ethernet) and a third peripheral port. It is the best controller to automate your observatory.

With the Platypus and Firefly, you will be able to:

-Leave the computer (and the rest of equipment) off, and, from a remote location, turn them on.
-Check and control your observatory's roll-of roof,
-If the main observatory computer hangs , Platypus can automatically reset it - or maybe close the roof and switch everything off

... apart from observatory automation (with the Firefly add-on), the Platypus has all the features of the Armadillo (incidentally, the Armadillo can also drive the Firefly, but always from a local USB connection), managing up to 3 devices: focusers, camera rotators, filter wheels, the Firefly... up to 3 at the same time.

The Platypus can be accessed by local network and USB, and with concurrent connections: one computer via network and other via local USB, a few of them via network...

And, in the coming months, you'll be able to control your Platypus + Firefly from a smartphone (iPhone or Android) - open your roof while you're commuting back home!
