Seletek controller

Seletek is Lunatico's astronomical peripheral controller

• Focusing, up to two motors at the same time
• Filter wheel managing, up to two at the same time
• ... or one filter wheel and one focus motor
• Fan Control Available here.
  
  
  
  
  
  It includes output for two motors, several digital and analog inputs, and two temperature sensors (one internal, included, and an optional external, one), and its first use was for the control of a focus motor (but as already said it now controls two motors or filter wheels or combination), the one supplied by Lunático or others in the market (Robofocus or Moonlite motors currently supported). USB connection to PC (no need of RS232 port).
  
  

  
  
  

  Besides in a not very far future we are planning to make the necessary modifications that will allow us:
  

  • To Turn on and off devices (very useful when preparing the observatory automation). You can pay a look at the prototype relay board.
  • Rotate domes tracking the telescope position
  • Automatize a instrument rotator
  • And other utilities we could detect from your suggestions.
  
  
  
  Technical spcifications:
