• Hubble Bluetooth Digital Setting Circle system, combined with Sky Safari on
    an Android device (Tablet or Smart Phone) is the most powerful Digital
    Setting Circle system at an extremely affordable price.
  • 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.
  • It works with Sky Safari on iPad/iPhone/iPod when an optional Skyfi WiFi
    receiver is connected to SkyHub-B via the USB port!
  • 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.
  • You can find any satellite or comet!
  • 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.
  • The regular, or rechargeable 6 AA external batteries box, or a 9V internal
    battery can be used. About 20-30 hours operation time for the regular and
    rechargeable external batteries. The operations times are based on
    household Duracell MN1500 and DC1500.

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.

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.
