Seletek LIMPET controller

Seletek LIMPET controller

Seletek LIMPET, the smallest and most recent Seletek! ASCOM, INDIGO and INDILib compliant!

With a small 12V battery and the wifi interface, no cables coming out of the telescope!

• new focuser controller from:
  • • any astronomy program (ASCOM and INDILib drivers available)
    • your smartphone
    • your computer’s web browser
• can alternatively control a camera rotator (with our Windows software and ASCOM)
• very small enclosure
• central hole to easily attach the Limpet to the telescope using a single screw
• Wifi and USB connection
• Very low power requirements (30mA idle connected to wifi, 530mA focusing with our standard motor)
• Optional external wifi antenna needed if the wifi signal is weak – if the wifi access point is in the observatory it won’t be necessary
• Optional external temperature sensor
• all the time-proven Seletek Armadillo and Platypus software will work with it. Just one device at any time.
• Including a screw locking 2.1x 5.5mm jack for safe attachment of power cable
• 5.5 / 2.1mm standard jack, center positive, 12V dc (13.8V, as supplied by some batteries, is valid)
• ASCOM, INDIGO and INDILib enabled
• focus from your smartphone via web interface (NEW!)

Why is an external controller like the Armadillo, Platypus, Tarsier or Limpet better than an “all in one” (focuser with embedded motor and cables)?

With the Limpet you can: Control one focus motor Control one rotator motor With our free program “PinByPin“: 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, as ones of the ZeroDew system. Control of the VSI’s “Zerotator”, or the Astrodon “TAKometer” “Seletek à la carte” allows you to customize your Seletek (original or Armadillo or Limpet) to match you specific needs … and we always accept suggestions, please contact us at [email protected]. And in the next future… – optional physical limit switches – ASCOM Alpaca (inside)		The focuser, rotator and filter wheel software are ASCOM compliant.
		And Linux / INDIlib driver for the focuser!
		And, also INDIGO driver for the focuser!
