Hubble SkyHub-B 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 SkyHub-B on your Windows XP/Vista/7.
  • It also supports USB connection with MAC Book, so you can use Sky Safari on a Mac directly connected with SkyHub-B via a USB cable.
  • It supports Bluetooth to Android and Windows devices, and USB connection to MS Windows and Mac OS devices(Mac Book). It does NOT support the Bluetooth connection to any iOS device.
  • The Hubble SkyHub-B is a Bluetooth/USB 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.
  • Sky Safari (Pro) features 15.3 million stars, 740,000 galaxies, and 550,000 solar system objects, including all the comets and asteroids ever discovered.
  • Hubble SkyHub-B Digital Setting Circle comes with revolutionary high resolution (8192 PPR), extremely compact, and highly energy efficient ball bearing encoders. It is 80% more power efficient, and is only about 15% size of a traditional encoder.

  • Hubble SkyHub-B should be compatible with most of Android devices with built- in Bluetooth profile supporting Bluetooth 2.0 or higher. In case that your device is not compatible with Sky Hub, please try another device of different model or brand. If you want to return the system for whatever reason, we will honor a full refund (excluding the shipping cost for both ways). You should determine if the SkyHub-B is compatible with your Android device right after the assembly of the transceiver unit but before installing the system to your scope. The returned unit must be in the original (sellable) condition.
  • The MS Windows applications support is provided "AS IS".


Q: Does SkyHub-B work with my non Hubble UL telescope?

A: Yes, it actually work with any kind of telescope supported by your planetarium software, such as German EQ Mount, Equatorial Fork, Alt-Az Fork (Dobsonian) and EQ platform.

Q: Does SkyHub-B work with my own encoders?

A: It should work with any TTL-compatible quadrature encoders such as Single-ended US digital encoders, S1/S2/S3/S5/S6. By default, our encoder housing and bracket supports metric 6mm diameter encoder shaft.


  • Please specify Bracket for UL14/16, or UL18/UL20. For people who have not purchased any UL system, we will ship it with the bracket for UL14/16.
