Hubble SkyHub2 with our revolutionary encoders (The Android Tablet and Sky Safari in the picture are NOT included!)

  • Thanks to David Ek's wonderful ASCOM DSC driver, now you can enjoy many wonderful Windows based Astronomy software such as TheSky, Sky Map Pro, Earth-Centered Universe, Cartes du Ciel (Sky Chart), and Stellarium with SkyHub2 on your Windows XP/Vista/7.
  • It supports WiFi and Bluetooth to Android and Windows devices. It does NOT support the Bluetooth connection to any iOS device.
  • It works with Sky Safari on iPad/iPhone/iPod with WiFi!
  • The Hubble SkyHub2 is a WiFi/Bluetooth based controller which constantly monitors the position of the telescope via two encoders attached to two telescope axes. This position information is sent to an Android, Windows, iOS or Mac OS based device, and the scope’s pointing direction is then updated on the screen in real time via your favorite planetarium software.
  • Just point your scope to any star, and touch the same star on the Sky Safari, which will complete the one star alignment. Then you simply touch any star on the screen, and move you scope until your Scope’s position mark exactly meets the target star on the screen …“Ding”, done!
  • Optionally, you can perform a two star alignment at any time for better pointing accuracy.
